Safety CPU module

The safety CPU module that is compliant with internationally recognized safety standards enables both general control and safety control which can safely stop a machine. In cooperation with safety drives, a system ensuring safety while avoiding frequent mechanical stops can be configured.

ISO 13849-1 PL eIEC 61508 SIL 3

  • *1.The program capacity of the safety control is 40K steps.

Interface

Features<sup>Safety and general control in one CPU module</sup>

  • One system
  • Space-saving
  • Cost reduction
  • Using the safety CPU module on CC-Link IE TSN or CC-Link IE Field Network can execute both general and safety programs, enabling easy integration into one control system
  • Installation of separate programmable controllers and networks is unnecessary, saving on space and costs

General and safety programs in the common engineering platform

  • Integrated program
  • In engineering software GX Works3, general programs and safety programs are included in the same project folder
  • The need to manage multiple project folders is eliminated
