Siemens 6DL1193-6BH00-0SM0 — SIMATIC ET 200SP HA Carrier Module (Single IM) | 24V DC | –40°C to +70°C | New Original

When engineers spec distributed I/O for process automation — refinery DCS expansions, chemical plant PROFINET I/O drops, offshore platform control upgrades — the infrastructure components that hold the interface modules often get less attention than the I/O cards themselves. That's usually fine, until a carrier module is missing from a site delivery, a system expansion hits an unexpected hardware gap, or a spare parts audit reveals a single carrier where a redundant one was needed. The 6DL1193-6BH00-0SM0 is one of those foundational components: the single-carrier version of the ET 200SP HA interface module carrier — the mechanical and electrical backbone that seats one IM (interface module) in an ET 200SP HA station.

Understanding what this carrier does, what "single" vs "redundant" means, and which ET 200SP HA configurations require it makes the difference between ordering the right part the first time and a weeks-long delay waiting for a correction shipment.

Order Number Decoded — 6DL1193-6BH00-0SM0

6DL — SIMATIC ET 200SP HA product family. "6DL" is the order number prefix exclusive to the ET 200SP HA series — the High Availability variant of the ET 200SP distributed I/O system, engineered for process automation applications requiring extended temperature range, hazardous area suitability, and high-availability redundancy configurations. This is distinct from the standard ET 200SP ("6ES7 1xx" prefix), which is the discrete manufacturing / standard process variant.

1193 — Carrier and terminal block sub-family within ET 200SP HA. Within the 6DL family, "1193" identifies passive infrastructure components — carrier modules, terminal blocks, bus adapters, and power bus covers — as opposed to active I/O modules (which carry "1131," "1134," "1136," etc. prefixes depending on I/O type).

6BH00 — Carrier module for IM (interface module), base variant. "6B" designates the carrier module type specifically for holding interface modules (as opposed to "6G" carriers, which hold I/O modules). "H" indicates the IM carrier housing form. "00" is the base configuration code.

0SM0 — Single carrier with server module, standard version. This suffix is the critical differentiator: "S" = Single — this carrier holds exactly one interface module. The alternative is "0RM0" — the Redundant carrier that holds two interface modules side by side for IM redundancy. Ordering "0SM0" when "0RM0" is required (a redundant HA station) will result in an installation that cannot achieve IM-level redundancy without a second carrier.

The "M" in "0SM0" indicates the included server module — a passive plug that occupies the unused server module slot and is required for proper backplane bus termination in the ET 200SP HA station. The server module is included with every 6DL1193-6BH00-0SM0 delivery from Siemens.

What Is the ET 200SP HA — And Why It's Different from Standard ET 200SP

The standard SIMATIC ET 200SP (6ES7 prefix) is Siemens' high-density distributed I/O platform for discrete and standard process automation — factory production lines, machine tools, packaging systems. It's fast, compact, and cost-effective.

The ET 200SP HA (6DL prefix, HA = High Availability) is a separate product line built for a different set of requirements:

Extended temperature range. Standard ET 200SP operates from 0°C to +60°C. The ET 200SP HA, including this carrier module, operates from –40°C to +70°C (horizontal mounting) — covering outdoor cabinet installations in arctic climates and hot-environment process plants without active cabinet cooling.

Hazardous area certification. ET 200SP HA components carry approvals for use in hazardous locations (Zone 2/Division 2 class), making them suitable for direct installation in process areas classified as potentially explosive — refineries, gas plants, offshore platforms — without requiring a separate purged/pressurized enclosure.

High-availability redundancy support. The ET 200SP HA architecture supports both I/O module redundancy (redundant terminal blocks allow two I/O modules to serve the same field terminals) and IM-level redundancy (the redundant carrier 6DL1193-6BH00-0RM0 holds two interface modules for controller-side redundancy). This makes the system suitable for SIL-rated and high-availability process control applications.

PCS 7 and S7-1500 HA integration. ET 200SP HA is the recommended distributed I/O platform for SIMATIC PCS 7 process control systems and S7-1500 HA (High Availability) controllers. Standard ET 200SP is not the correct hardware for HA system configurations.

Single Carrier vs Redundant Carrier — Choosing the Right One

This is the most common source of ordering errors with ET 200SP HA carrier modules. The choice depends entirely on whether the station uses a standard (simplex) IM or a redundant IM configuration:

6DL1193-6BH00-0SM0 (this module — Single carrier):

Holds one interface module
Used in standard (non-redundant) ET 200SP HA stations where the I/O drop has a single connection to one controller or one PROFINET network
Appropriate for applications where I/O availability is managed at the controller level (e.g., S7-1500H paired controller redundancy with independent I/O paths) but the individual I/O station itself does not require IM-level redundancy
Also used in configurations where I/O module redundancy (redundant terminal blocks) is implemented at the I/O slot level without IM redundancy

6DL1193-6BH00-0RM0 (Redundant carrier — different order number):

Holds two interface modules side by side
Used when IM redundancy is required — both IMs connect to different controllers or different PROFINET paths, providing continued I/O access if one IM or one PROFINET path fails
Required for the highest-availability configurations in PCS 7 redundant systems

If your system design document or hardware configuration shows a redundant IM configuration (two IM 155-6 PN HA modules on a single station), you need the 0RM0 redundant carrier. If the station has a single IM, 0SM0 is correct.

Role of the Included Server Module

Every 6DL1193-6BH00-0SM0 ships with a server module included. This small passive component is not optional — it must be installed in the server module slot on the carrier for the ET 200SP HA station to function correctly.

In the ET 200SP HA architecture, the server module terminates the backplane communication bus at the appropriate point in the station and provides the physical slot structure that the TIA Portal hardware configuration recognizes as the station boundary. Without the server module properly seated, the backplane bus is unterminated and the station will not initialize correctly.

The server module also stores I&M (Identification & Maintenance) data — electronic nameplate information that allows TIA Portal and SIMATIC PDM to identify the station, read its order number, firmware version, and maintenance history, and compare the physical hardware against the programmed configuration. This I&M data capability is referenced as a feature in the official datasheet and is part of why ET 200SP HA components support asset management functions in PCS 7 and S7-1500 HA systems.

Compatible Interface Modules

The 6DL1193-6BH00-0SM0 single carrier is designed for the SIMATIC ET 200SP HA interface module family. The primary interface module used with this carrier in current installations is the IM 155-6 PN HA series — the PROFINET interface module for ET 200SP HA stations. Compatible IM variants include:

6DL1155-6AU00-0AM0 — IM 155-6 PN HA, standard version
6DL1155-6AU00-0BM0 — IM 155-6 PN HA, with bus adapter slot for PROFINET topology flexibility

The carrier's mechanical design — 100mm wide, 204mm tall, with the backplane bus connector and power bus contacts — is specifically dimensioned for ET 200SP HA interface modules. It is not interchangeable with standard ET 200SP carriers (6ES7 193-6 prefix) or with ET 200SP HA I/O module carriers (6DL1193-6GA00 or 6DL1193-6GC00 series).

Typical Applications

Offshore oil and gas platforms — ET 200SP HA I/O stations in Zone 2 classified process areas, where the hazardous area certification of the carrier and IM allows direct installation without purged enclosures. The –40°C lower operating limit covers cold-start conditions on platforms in northern latitudes.

Onshore refineries and petrochemical plants — distributed I/O drops for PCS 7 DCS systems in process units, where the extended temperature range handles hot summer ambient conditions in outdoor junction boxes and the HA architecture supports the high-availability requirements of continuous process operation.

LNG and gas processing facilities — I/O stations supporting compressor control, separator level, and flow metering in areas with both low-temperature cold-start requirements and classified area ratings.

Power generation plants — distributed I/O for turbine control, boiler monitoring, and balance-of-plant systems using S7-1500 HA controllers, where the single carrier is appropriate for standard (non-redundant IM) I/O drops.

Chemical and specialty chemical plants — process I/O for batch reactors, distillation columns, and utility systems in PCS 7 installations that require both hazardous area rating and the extended environmental tolerance of the HA series.

Maritime applications — the NK (Nippon Kaiji Kyokai) and CCS (China Classification Society) certifications noted in the official datasheet make this carrier suitable for marine vessel automation applications requiring class society approval.

❓ FAQ — Siemens 6DL1193-6BH00-0SM0

Q1: What's the difference between 6DL1193-6BH00-0SM0 (single) and 6DL1193-6BH00-0RM0 (redundant) — which one do I need?

The "S" in "0SM0" stands for Single — this carrier holds one interface module. The "R" in "0RM0" stands for Redundant — that carrier holds two interface modules for IM-level redundancy. Your choice depends on your system's IM configuration. If the TIA Portal hardware configuration or PCS 7 project shows a single IM on the station, use the 0SM0. If the design shows redundant IMs (two IM 155-6 PN HA modules on one station for dual-path PROFINET connectivity), use the 0RM0. This is the most common ordering error with ET 200SP HA carrier modules — checking the actual hardware configuration in TIA Portal before ordering is the reliable way to confirm which carrier is needed.

Q2: Why is this product "ET 200SP HA" rather than standard "ET 200SP" — are they interchangeable?

No, they are not interchangeable. ET 200SP HA (6DL prefix) and standard ET 200SP (6ES7 prefix) are separate product families with different hardware, different software configuration procedures, and different certifications. ET 200SP HA is specifically designed for process automation — extended temperature range (–40°C to +70°C vs 0°C to +60°C for standard), hazardous area certification for Zone 2/Division 2 locations, high-availability redundancy support, and compatibility with SIMATIC PCS 7 and S7-1500 HA. The carrier modules, interface modules, I/O modules, and terminal blocks from each family are physically and electrically different and cannot be mixed on the same station. If you're expanding or maintaining a standard ET 200SP installation, the 6DL components from the HA series are not the correct parts.

Q3: A server module is listed as included — what is it and what happens if it's missing or lost?

The server module is a small passive plug that inserts into a dedicated slot on the carrier. It terminates the ET 200SP HA backplane bus and provides the electronic boundary marker that the system uses to identify the end of the station. Without a properly seated server module, the backplane bus is unterminated and the station will not initialize — TIA Portal's online device diagnostic will show a hardware configuration mismatch, and the IM will generate a station fault. If the server module is lost or damaged, a replacement can be ordered separately. However, since the server module is included with every new 6DL1193-6BH00-0SM0 carrier, ordering a new carrier resolves both needs at once when a replacement station is being built.

Q4: Can this carrier be used in a classified (ATEX/IECEx) hazardous area directly?

The 6DL1193-6BH00-0SM0 carries a "General Product Approval — For use in hazardous locations" certification, per the official Siemens datasheet. The specific area classification (Zone 2 / Division 2 for non-incendive operation is the typical ET 200SP HA rating) and the complete installation requirements are specified in Siemens' ET 200SP HA system manual and the associated Ex approval documentation available on the Siemens Industry Online Support portal. Always verify the complete approval documentation against your site's specific area classification before installing any ET 200SP HA component in a hazardous area — the carrier's approval must be combined with the interface module's and I/O modules' own hazardous area certifications, and the installation must follow the Ex installation requirements specified in the approval documentation.

Q5: What is the operating temperature range, and does mounting orientation matter?

According to the official Siemens datasheet, operating temperature ranges differ by mounting orientation: horizontal installation: –40°C to +70°C; vertical installation: –40°C to +60°C. The 10°C difference in the upper limit is due to thermal convection — in horizontal mounting (the backplane horizontal), heat dissipation from the electronics is less efficient than in vertical mounting (the standard orientation for ET 200SP HA panels, with the backplane vertical and natural convection upward). For most panel installations, vertical mounting is standard and the –40°C to +60°C range applies. The lower limit of –40°C is relevant for outdoor cabinet applications in cold climates, covering conditions where the cabinet may be unpowered and exposed to outdoor winter temperatures before a cold start.

Q6: How does this carrier module fit into a TIA Portal hardware configuration?

In TIA Portal, the ET 200SP HA station is configured under the SIMATIC ET 200SP HA I/O system. The carrier module itself appears in the hardware catalog as the "IM carrier module, single" and is placed in the configuration as the mechanical host for the interface module. The TIA Portal configuration then defines which IM (e.g., IM 155-6 PN HA) sits in the carrier, followed by the I/O module slots. The carrier's I&M data support means TIA Portal can read the carrier's electronic identification data during an online comparison — flagging any physical hardware that doesn't match the programmed configuration. For PCS 7 projects, the ET 200SP HA station configuration follows the same general procedure but within the SIMATIC Manager / PCS 7 hardware configurator.

Q7: Is this carrier compatible with standard ET 200SP I/O modules (6ES7 prefix)?

No. The 6DL1193-6BH00-0SM0 is part of the ET 200SP HA system and is mechanically and electrically specific to ET 200SP HA components. Standard ET 200SP I/O modules (6ES7 131, 6ES7 132, 6ES7 134, etc.) use different carrier and terminal block dimensions and different backplane bus connectors. They cannot be mounted on ET 200SP HA carriers. Similarly, ET 200SP HA I/O modules (6DL1131, 6DL1132, 6DL1134, etc.) cannot be mounted on standard ET 200SP carriers. The two product families share a similar architecture concept but are not physically interchangeable — this is important to verify before ordering spare parts for a mixed or uncertain inventory, where the "6DL" vs "6ES7" prefix is the reliable indicator of which family each component belongs to.
