In addition to safety input and output modules, the ET 200S product line also includes safety frequency converters, motor starters, power modules, contact multipliers and interface modules.
An ET 200S station can hold both safety and standard input and output modules.
Supported safety buses:
PROFIBUS via IM 151-1 HF
PROFINET via IM 151-3 PN HF and IM 151-3 PN FO with LWL interface
Field of Application
The ET 200S is used for distributed expansion of the safety S7 controllers.
Digital inputs / outputs
For connecting digital sensors/encoders and/or loads/actuators
For safety-related shutdown of standard digital outputs (DOs) up to category 3 (EN 954-1)
For monitoring and short-circuit protection of the supply voltages for the loads and encoders
Safe standstill, safely reduced speed and safe brake ramp for encorderless asynchronous motors
