ET 200pro Failsafe I/Os

The failsafe modules of ET200pro can be used to implement the safety-related application requirements as an integral part of the overall automation.

The safety functions required for fail-safe operation are integrated in the modules. The modules can be used for safety circuits up to Cat. 4/ SIL 3.ext.
Two PROFIsafe modules are available for connecting digital sensors/encoders and/or loads/actuators.

The available F-Switch enables disconnection of standard I/O modules and safe controlling of ET 200pro motor starters in conjunction with the ASM 400 V module.
