Overcurrent protection of the 20 mA inputs

The current inputs are protected against damage by overcurrent by an internal current limitation, currents > 30 mA may occur.

  • In the event of a fault, the current limiter must not be overloaded by a voltage > 30 V from the source device.
  • Overcurrent is displayed in the process image as "Overrange".
  • After occurrence, the error condition must be stopped immediately, the source device switched off or disconnected from the input terminal.
  • If the error condition persists for a longer period of time, the internal terminal current limitation reduces the absorbed signal current for thermal reasons, depending on the ambient conditions also below 20 mA.
