D2-12TR PLC Direct Koyo Relay Output Module D212TR New In Box
PRODUCT DETAILS
Product Description
D2-12TR — Koyo DirectLOGIC 205 Relay Output Module
If you're building or maintaining a DirectLOGIC 205 PLC system, the D2-12TR is one of the most versatile output modules in the DL205 lineup. With 12 relay output points, broad voltage compatibility, and a removable terminal block that makes field installation genuinely straightforward, it earns its place in control panels across manufacturing, material handling, and process automation environments alike.

Why Relay Outputs — And Why This Module
Transistor outputs are faster, but relay outputs remain the preferred choice for many real-world control tasks. They switch both AC and DC loads without requiring separate power supplies for each load type. More importantly, they provide true electrical isolation between the PLC logic and the field device — a practical advantage when controlling solenoid valves, contactors, indicator lamps, or small motors.
The D2-12TR covers an unusually wide voltage window: 5V to 240V AC and 5V to 30V DC. That flexibility means a single module type can handle a mix of 24VDC sensors, 110VAC coils, and 220VAC devices on the same rack, reducing the number of different spare parts you need to keep on hand.
Built for Real Maintenance Conditions
One of the less-discussed advantages of the D2-12TR is its removable terminal block. In practice, this makes a meaningful difference during installation and replacement — you can pre-wire the terminal block off the module, then snap it in when the module is seated. No need to disconnect field wiring to swap out a failed module during a plant shutdown. That kind of design consideration reflects the practical engineering behind the DirectLOGIC 205 platform.
The two replaceable 4A slow-blow fuses add another layer of protection, allowing field personnel to restore operation after an overcurrent event without replacing the entire module.
Load Types & Contact Life Reference
| Load Type | Voltage | Resistive | Inductive |
|---|---|---|---|
| DC Loads | 24VDC | 1A / 500k cycles | 1A / 100k cycles |
| DC Loads | 110VDC | 1A / 500k cycles | 1A / 200k cycles |
| AC Loads | 220VAC | 1A / 350k cycles | 1A / 100k cycles |
Typical Applications
The D2-12TR fits naturally into a wide range of automation roles:
- Controlling conveyor motors and actuators in packaging lines
- Switching solenoid valves in fluid handling systems
- Driving indicator lights and alarm horns on HMI panels
- Interfacing PLCs with legacy AC-powered field devices
- General-purpose discrete output in process control panels
Frequently Asked Questions
Q: What PLC platforms is the D2-12TR compatible with?
A: It is designed for use with the AutomationDirect DirectLOGIC DL205 modular PLC series. It is also compatible with the Do-more PLC platform. It does not plug directly into DL06, DL105, or other DirectLOGIC families without an appropriate base/rack.
Q: How many output points does the D2-12TR provide, and how are they grouped?
A: The module provides 12 usable output points, divided into two isolated commons of 6 points each. It occupies 16 points in the I/O map, with 4 unused addresses reserved by the system.
Q: Can I mix AC and DC loads on the same module?
A: Yes — each common is independently isolated, so you can run DC loads on one 6-point group and AC loads on the other. However, you should not mix AC and DC within the same common group, as the commons are shared within each group.
Q: What is the maximum current this module can handle?
A: Each individual output point supports up to 1.5A resistive load. The maximum current per common (shared across 6 points) is 3A. Exceeding these values risks tripping the onboard slow-blow fuses or damaging relay contacts.
Q: What type of relay does the D2-12TR use?
A: The module uses Form A (SPST — Single Pole Single Throw) relay contacts. These are normally-open contacts that close when the output is energized.
Q: Does it include a terminal block, and can wiring stay connected during module replacement?
A: Yes, the D2-12TR includes a removable D2-16IOCON terminal block. Because the terminal block detaches from the module body, field wiring can remain in place when swapping the module — a significant time saver during maintenance.
Q: Are the fuses user-replaceable in the field?
A: Yes. The module uses two 4A slow-blow 5×20mm fuses that can be replaced by maintenance personnel without returning the module for service.
Q: What does "New in Box" mean for this listing?
A: The unit is factory-new, unused, and in original manufacturer packaging — not refurbished, not tested-used. It is ready for immediate installation.
