Controller Module FM 455

The universal solution for closed-loop control


The FM 455 controller module has 16 channels, and is suitable for universal use, e.g. for temperature, pressure, flow and level control.The FM 455 controller module for the SIMATIC S7-400 can also be used in PCS7 systems.

It offers:

  • a variety of preprogrammed control structures,    

  • a self-optimization function with which controllers can be quickly and easily optimized, and   

  • a backup function for problem-free operation in the event of a CPU stop/failure.

The module is available in two versions for controlling different actuators:     

  • FM 455 C as continuous-action controller for analog actuators

  • FM 455 S as step-action or pulse-action controller for the control of actuators via digital outputs
