Allen-Bradley 1745-R2 Eight Point Relay Output Module

Allen-Bradley 1745-R2 Eight Point Relay Output Module is an eight-channel relay output card designed for use with Allen-Bradley SLC 500 controllers. It provides eight relay contacts you can energize from the PLC program to switch external devices, enabling multi-point control of loads such as solenoids, lamps, or other actuators in a single module. As part of the 1745 I/O family, the module integrates into a standard 1745 I/O backplane and shares the chassis addressing and communication methods common to SLC 500 systems. Each of the eight outputs operates as an independent relay channel, delivering a straightforward, mechanical switching interface between the processor and external circuits. For exact electrical characteristics, load ratings, wiring schemes, and compatibility details, refer to the official Rockwell Automation documentation specific to the 1745-R2 model.
