Siemens 6ES7194-4DD00-0AA0 is the SIMATIC ET 200pro CM IO 16xM12 fail-safe connection module for the EM 8/16 F-DI 24 V DC electronic module. It provides the field-connection interface for distributed fail-safe digital input signals.
The connection module must be selected together with the correct ET 200pro F-electronic module and station components. Safety integrity depends on the complete configured system, wiring, parameterization and proof of the installed safety function.
