If you only need to add a few inputs or outputs to your SIMATIC S7-1200 G2 CPU, signal boards are a good alternative to signal modules. Signal boards are plugged directly onto the front of the controller and are available as digital and analogue input, output and mixing modules. Signal boards therefore also allow a subsequent expansion of the configuration without taking up additional space in the control cabinet.
