The SB 1232 analog output signal board permits the use of analog outputs.

This provides users with the following advantages:

• Optimal adaptation:
  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 output ranges permit the connection of actuators without additional amplifier.
• Flexibility:
  If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple.
