Product Description
Product Overview
The Allen-Bradley 1764-OW8 is an 8-point relay output module designed for use with MicroLogix 1500 PLC systems. This module provides isolated electromechanical relay outputs for controlling field devices such as solenoids, contactors, pilot lights, and interposing relays.
The 1764-OW8 uses Form C (SPDT) relay contacts, allowing both normally open and normally closed output wiring. Its relay-based design makes it suitable for mixed AC/DC loads and applications where electrical isolation is required.
Functional Description
The 1764-OW8 relay output module converts PLC control logic into physical relay contact closures. Each output channel operates independently, driven by internal coil logic from the MicroLogix backplane. Status LEDs indicate commanded output states but do not monitor actual contact welding or load feedback.
Because the outputs are mechanical relays, external wiring conditions and load characteristics can affect perceived output behavior.
