Allen-Bradley 1771-OBD
16-Point DC Digital Output Module for PLC-5® Systems
Product Description
The 1771-OBD is a 16-point DC digital output module designed for use in PLC-5® systems. It provides non-isolated sourcing outputs for controlling field devices such as solenoids, relays, and indicator lamps. Operating within a voltage range of 10–60 VDC, the module is suitable for medium-voltage DC control applications. Each output is capable of handling both resistive and pilot-duty loads.
