Allen-Bradley 1771-OMD/B AC Output Module — Precision Control for PLC-5 Automation

The Allen-Bradley 1771-OMD/B is a high-performance AC output module engineered for seamless integration with PLC-5 programmable logic controller systems. Designed to drive AC loads directly from your control logic, this module delivers reliable switching for solenoids, contactors, motor starters, and indicator lamps in demanding industrial environments.

Technical Specifications

  • Catalog Number: 1771-OMD/B
  • Output Type: AC Triac (isolated)
  • Number of Outputs: 8 points per module
  • Voltage Range: 85-265V AC, 47-63 Hz
  • Current Rating: 2A per point (resistive load)
  • Isolation: 1500V AC optical isolation between logic and field
  • Backplane Current: 150 mA @ 5V DC
  • Operating Temperature: 0-60 °C (32-140 °F)
  • Mounting: 1771 I/O chassis compatible

Application Scenarios

Manufacturing & Assembly Lines: Control conveyor motors, pneumatic actuators, and sorting mechanisms with fast, repeatable switching cycles.

Process Automation: Interface with valve actuators, pump starters, and heating elements in chemical, food & beverage, and pharmaceutical plants.

Building Automation: Manage HVAC dampers, lighting circuits, and access control systems through centralized PLC-5 logic.

Material Handling: Drive lift gates, diverters, and robotic end-effectors in warehousing and distribution centers.

Innovative Solutions

Hot-Swap Capability: Replace or add modules without powering down the entire chassis, minimizing downtime during maintenance windows.

Diagnostic LEDs: Per-point status indicators simplify troubleshooting and reduce mean-time-to-repair (MTTR) by up to 40%.

Surge Protection: Built-in RC snubber networks absorb inductive kickback, extending contact life and protecting downstream devices.

Legacy System Modernization: Retrofit aging relay panels with solid-state control while preserving existing PLC-5 architecture and programming investments.

Installation & Integration

Mount the 1771-OMD/B in any available slot of a 1771 I/O chassis. Configure addressing via the backplane switch, then map outputs in RSLogix 5 or RSLogix 500 software. Wiring terminals accept 14-22 AWG copper conductors; torque to 7 lb-in for optimal contact.
