WESTERN 1781-0M5Q Output Module

The Western Reserve Controls 1781-0M5Q Output Module is a panel- or DIN-mounted AC output switch and signal interface device for PLC and industrial automation systems. It is an OAC5Q output module designed to provide AC output switching and control in PLC racks, industrial control panels, and machine automation equipment that require reliable actuation of AC signals. Its part numbers are 1781-0M5Q and 17810M5Q, and the module is intended for process and machine control tasks within industrial automation environments. This output module is commonly used in machine control systems and process installations where AC outputs drive relays, contactors, or other actuators, making it suitable for both panel-mounted control panels and DIN rail applications in industrial settings. Common replacements include WESTERN 1771-OA Output Module, Opto 22 OAC5Q Output Module, and Siemens SIMATIC Digital Output Module, reflecting its role in cross-brand compatibility for retrofits and system maintenance.
