SIMATIC S7-1500 / ET 200MP Signal modules
The signal modules or I/O modules provide the interface between the controller and the process. The controller detects the current process status by means of the connected sensors and triggers the corresponding actuator reactions.
The digital and analog modules provide exactly the inputs/outputs that are required for the respective task. They can be used both centrally, i.e. directly on the CPU, as well as distributed in the ET 200MP I/O system. 25 mm and 35 mm modules are available.
