The Allen-Bradley 1771-A3B is a 16-point DC output module for Allen-Bradley SLC-500 PLC systems. It provides sixteen 5.25 V DC output channels with a total current rating of 24 A, suitable for switching low-voltage DC loads such as relays, coils, and small actuators from the PLC I/O backplane. Intended for plug-in installation in a standard 1771 rack backplane, this module integrates with the controller to deliver reliable, discrete DC outputs for automation tasks.
