Signal Boards
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:
