Signal Boards

Mounting a signalboard to a S7-1200 CPU

Signal boards are connected directly to the front of the CPU. They can be used where space is limited or if only a few additional inputs/outputs are required.

  • Each S7-1200 CPU can be modularly expanded by a signal board.

  • This does not increase the mounting space required for the controller.

  • The portfolio includes digital inputs, digital outputs, mixed digital IOs, analog inputs and analog outputs.

Or browse through the image gallery to see how easily signal boards are mounted:
