Controllers MELSEC-QS/WS Series Safety Relay Modules (Out of production)
This Series has been discontinued in March 2025.
Safety relay module
The safety relay module integrates the emergency stop circuit and the restart circuit with a double safety relay. A basic safety function can be realized with just wiring, eliminating the need for programming and parameter settings. Furthermore, the number of I/O points can be increased by adding extension modules.
