The Allen-Bradley 1771-OW Output Module is an eight-point digital output card for PLC-5 backplanes that uses electromechanical relays to switch loads at 120 VAC. As a selectable contact output module in the 1771 I/O family, it provides eight individually controlled relay contacts suitable for energizing relays, solenoids, or motor starters through a PLC-5 I/O chassis. It is designed for use with the 1771 I/O backplane and can be installed alongside other 1771 modules in the same chassis to form a complete control rack.
