• User-friendly wiring:
  Sensors and actuators are connected via two separate 48-pin front connectors.
• LEDs:
  • Red internal fault LEDs
  • Red external fault LEDs
  • Green LEDs for digital input status display
  • Yellow LED for indicating backup operation
• High-performance measured data acquisition:
  The module has 16 analog inputs for analog value acquisition and disturbance variable input as well as 1 additional analog input for temperature compensation when used with thermocouples.
• Various encoders can be used:
  Thermocouples, Pt 100, voltage encoders, current encoders.
• Extensive I/O:
  • FM 455 C: 16 analog outputs for analog actuators
  • FM 455 S: 32 digital outputs for motor-driven actuators or binary-controlled actuators.

The 24 V DC supply for the actuators is applied externally.
