Safety controller

This compact new safety controller complies with ISO13849-1 PLe and IEC61508 SIL3 safety standards.
The most suitable application of MELSEC-WS is to ensure safe operation of stand-alone machines or systems.
To meet your system configuration, it allows you to have additional I/O points of up to 144. Also, you can easily make settings and create logic by using the Setting and Monitoring Tool exclusively provided for the controller.

  • CPU module(WS0-CPU1) supports Flexi Link with EFI for safety communications between safety controllers
    Safety communications between safety controllers can be easily established at a low cost just by connecting the CPU modules with dedicated cables (Flexi Link cables).
    Using Flexi Link, safety communication can be conducted between up to four safety controllers.
