Allen-Bradley 1771-OMD
16-Point AC Output Module for PLC-5 Series
Product Description
The Allen-Bradley 1771-OMD is a 16-point AC output module designed for use with the PLC-5 series and installed in a 1771 I/O chassis. It provides discrete control of external AC devices such as solenoids, contactors, and motor starters. Each output channel is individually fused, and the module is conformally coated for enhanced environmental protection. It receives power through the chassis backplane and supports rack mounting in industrial control systems.

Product Questions
- What types of loads can the 1771-OMD control? It is suitable for controlling AC loads such as solenoids, contactors, relays, and motor starters rated within the module’s voltage and current specifications.
- Are the outputs protected against overcurrent? Yes. Each output channel is individually fused to protect against overcurrent conditions.
- Can the 1771-OMD be used in high-density I/O configurations? Yes. It supports 16 output channels in a single slot, making it suitable for high-density applications within the PLC-5 architecture.
- Is the 1771-OMD compatible with all PLC-5 processors? It is compatible with PLC-5 processors that support the 1771 I/O chassis and addressing schemes. Addressing mode must be considered when mixing modules.
