SIEMENS S7-1200 I/O modules SM 1223 digital input/output modules

Overview

  • Digital inputs and outputs as supplement to the integral I/O of the CPUs
  • For flexible adaptation of the controller to the relevant task
  • For subsequent expansion of the system with additional inputs and outputs

ApplicationSM 1223 digital input/output modules

Digital input/output modules permit:

  • Connection of the controller to digital signals of the process
  • Output of digital signals from the controller to the process

This provides users with the following advantages:

  • Optimum adaptation:
    With signal modules which can be mixed as desired, users can adapt their controllers exactly to the relevant task. This avoids superfluous investments. Modules with 8, 16, and 32 input/output channels are available.
  • Flexibility:
    If the task is expanded subsequently, the controller can be upgraded. Updating of the user program is extremely simple

Function

The SM 1223 digital input/output signal modules convert

  • the level of the external digital signals from the process into the internal signal level of the S7-1200 and
  • the internal signal level of the S7-1200 into the external signal level required by the process.
