Overview
The 1771-OBD/C is a Relay Output module that interfaces with a PLC system to send output signals to various external devices such as motors, solenoids, and valves. It provides multiple relay contacts for on/off control of field devices, allowing the PLC system to act as the brain in the automation process, triggering physical actions in the field.
