  • Digital inputs as a supplement to the integral I/O of SIMATIC S7-1200 CPUs
  • Can be plugged directly into the CPU


The SB 1221 digital input signal boards enable connection of the controller to digital process signals.


The Signal Boards are plugged straight into the holder on the front of the S7-1200-CPU.

  • Mounting:
    Signal Boards are plugged direct into the SIMATIC S7-1200-CPU and linked electrically and mechanically with the CPU in this way.
  • The installation dimensions of the CPU remain unchanged.
  • On all Signal Boards, replacement is facilitated by removable terminals ("permanent wiring").


The SB 1221 digital input/output signal boards convert the level of the external digital signals from the process to the internal signal level of the S7-1200.
