SIMATIC Factory Safety

The ET 200S I/O system – Safety digital input/output modules and power modules

Different PROFIsafe digital I/O and one PROFIsafe relay module are available for connecting digital sensors/encoders and/or loads/actuators.

Power modules are used for monitoring and short-circuit protection of the load and encoder supply voltages. These are fed in over the TM-P terminal modules to the self-assembling voltage buses.
