Procurement teams operating in Oil & Gas, Automotive, Food & Beverage, and Power Generation sectors consistently rely on this module to sustain uptime in aging control architectures. Its conformal-coated PCB (the /D designation) provides enhanced resistance to moisture, dust, and corrosive atmospheres — a specification that standard variants cannot match. Whether you are sourcing for planned maintenance or emergency breakdown recovery, this Industrial Automation spare part ships with full traceability documentation upon request.

With 32 electronically protected sourcing outputs, optical isolation, and individual LED diagnostics per channel, this Control Module eliminates guesswork during commissioning and fault-finding. Contact our team today for pricing, lead time, and datasheet access.

Technical Specifications & Selection Guide

Selection Tip: Choose the 1746-OB32/D over the standard 1746-OB32 when your installation environment involves humidity, chemical vapors, or airborne particulates. The conformal coating significantly extends service life in such conditions without any change to wiring or programming.

Typical Application Scenarios

✅ Automotive Manufacturing: High-density output requirements on robotic welding lines and body assembly conveyors demand modules that can switch dozens of solenoids and actuators simultaneously. The 1746-OB32/D consolidates 32 outputs into a single rack slot, reducing chassis footprint and simplifying cable management in space-constrained control panels.

Power Plants & Utilities: Auxiliary control systems in power generation facilities require robust isolation between field devices and the PLC backplane. The 1500V optical isolation of this Control Module protects the SLC 500 processor from high-energy transients common in switchgear and motor control center environments.

✅ Oil & Gas Processing: Offshore platforms and onshore refineries expose electronics to salt spray, H , and hydrocarbon vapors. The conformal-coated /D variant of this Industrial Automation module withstands these aggressive atmospheres, making it the preferred Original Spare Parts choice for hazardous area control panels.

✅ Food & Beverage Packaging: Washdown environments and frequent sanitization cycles create humidity challenges for standard PCBs. The 1746-OB32/D’s protective coating ensures reliable operation in packaging lines where moisture ingress is a persistent maintenance concern.

✅ Material Handling & Logistics: Sortation systems, automated storage and retrieval (AS/RS), and conveyor networks require precise, high-speed discrete output control. This module’s sub-millisecond response times and per-channel LED diagnostics accelerate both commissioning and troubleshooting on complex material flow systems.

Core Features & Technical Advantages

• 32 Electronically Protected Sourcing Outputs — Heavy-duty overcurrent and short-circuit protection on every channel prevents cascading failures in high-density wiring scenarios.
• Conformal Coated PCB (/D Designation) — Robust moisture, dust, and chemical resistance extends module service life in harsh industrial atmospheres beyond standard variants.
• 1500V Optical Isolation — Precision galvanic separation between field wiring and the SLC 500 backplane eliminates ground loop interference and protects the PLC System from field-side faults.
• Individual Per-Channel LED Diagnostics — Rapid visual status indication on all 32 outputs accelerates fault isolation during commissioning and unplanned downtime events.
• Removable 36-Pin Terminal Block — Pre-wire the terminal block before module installation; swap the module without disturbing field connections, minimizing Mean Time to Repair (MTTR).
• Single-Slot Form Factor — Maximizes SLC 500 chassis density; 32 outputs in one slot versus multiple lower-density modules reduces hardware cost and rack space consumption.
• RSLogix 500 / RSLogix Micro Compatible — Plug-and-play integration into existing SLC 500 PLC System configurations with no additional licensing or firmware requirements.
