Product Description

Koyo D2-16ND3-2 — 16-Point 24VDC Discrete Input Module for DirectLogic 205

This listing is for a brand-new, factory-sealed Koyo (AutomationDirect) D2-16ND3-2 discrete input module — unused, unopened, and ready for immediate deployment in industrial automation environments.

What Is the D2-16ND3-2?

The D2-16ND3-2 is a high-density digital input module designed for use with the DirectLogic 205 (DL205) and Do-more PLC platforms. It accepts 16 discrete DC input signals simultaneously, making it one of the most efficient I/O expansion solutions available for Koyo-compatible control systems.

Whether you're upgrading an existing panel or commissioning a new machine line, this module delivers reliable, noise-resistant signal acquisition at 24 VDC — the industry standard for industrial sensor interfaces.

Why the D2-16ND3-2 Stands Out

Dual-mode flexibility — The sink/source compatible design means this module works with both NPN and PNP field devices without requiring separate hardware for different sensor types.

Isolated commons for signal integrity — With 2 electrically isolated commons (8 points each), the module allows mixed-voltage field wiring scenarios while protecting the controller from cross-circuit interference.

Tool-free terminal removal — The European-style snap-off terminal block lets technicians remove and rewire field connections without disturbing the module or the backplane, dramatically reducing maintenance downtime.

Drop-in compatibility — This module slots directly into any standard DL205 base and is recognized immediately by the DL240, DL250, and DL260 CPU families.

Condition & Packaging

This unit is new and factory sealed — not refurbished, not pulled from service. The original Koyo/AutomationDirect packaging is intact, and the removable terminal block is included as standard.

For facilities with strict traceability or warranty requirements, factory-sealed stock ensures full manufacturer specifications are guaranteed from day one.

FAQ

Q: Is this module compatible with the DL205 base? Yes. The D2-16ND3-2 is designed specifically for the DirectLogic 205 (DL205) series and mounts directly into any standard DL205 expansion base without adapters.

Q: Can it work with both NPN and PNP sensors? Absolutely. The module supports both sinking (NPN) and sourcing (PNP) input configurations, giving you flexibility when wiring mixed sensor environments.

Q: Does the terminal block come included? Yes. Every D2-16ND3-2 ships with a removable European-style terminal block already installed. No separate purchase is required.

Q: How many status LEDs does the module have? The module has 8 LED indicators. Because the module has 16 inputs, the LEDs are shared across two groups — you cycle between them to monitor all input states. This is standard for the DL205 platform's compact form factor.

Q: What is the safe input voltage range? The nominal operating voltage is 24 VDC, with an acceptable range of 20–28 VDC. The peak rated voltage is 30 VDC. Do not exceed this threshold to avoid damaging the input circuitry.

Q: Is this unit new or refurbished? This is a brand-new, factory-sealed unit. It has not been used, repaired, or remanufactured.

Q: Can I remove the terminal block for maintenance without rewiring? Yes. The snap-free terminal block design allows you to detach the wiring harness cleanly during module replacement or maintenance, then reconnect it without re-terminating any field wires.

Q: Is this module compatible with the Do-more PLC series? Yes. In addition to the DL205 platform, the D2-16ND3-2 is also compatible with AutomationDirect's Do-more PLC systems.
