The Allen-Bradley 1771-OZ is a PLC-5 relay contact output module designed to provide dependable discrete control signaling within the 1771 I/O chassis architecture. This single-slot module serves as an electromechanical interface between the programmable controller and external actuators, indicators, and control devices requiring isolated switching capability. It features built-in status indicators for each individual output channel to simplify diagnostic troubleshooting during system operation.
Engineered for standard industrial control environments, the 1771-OZ integrates directly into any available single slot within a compatible 1771 I/O chassis. The module handles low-voltage switching tasks while ensuring electrical isolation between the logic backplane and field-connected devices. During system power transitions, output channels may momentarily change state as the chassis power supply executes its initialization sequence.
