with analog signal modules, users can optimally adapt their controllers even to more complex tasks.
signal boards 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.
Direct connection of sensors and actuators:
Up to 14 bit resolution and different input/output ranges permit the connection of sensors and actuators without an additional amplifier
Flexibility:
If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple.
