12-HR-43-4 Product Description

12-HR-43-4 is a legacy industrial plug-in relay module used for CNC machine tools, servo control cabinets and turbine control systems. It provides isolated contact switching for digital interlock, enable signals, fault alarm and safety circuit control. This electromechanical relay has multiple contact sets, built into a plastic socket-mounted housing, to isolate low-voltage control signals and high-power load circuits. It is stocked as fully-tested spare replacement component for automation cabinet maintenance.
