Overcurrent protection of the 20 mA inputs

The current inputs are protected against damage due to overcurrent by an internal current limiter. Currents > 30 mA can occur.

  • To ensure that the current limiter is not overloaded in the event of a fault, no voltage > 30 V may originate from the source device.
  • Overcurrent is displayed in the process image as "Overrange". After occurrence
  • the error state must be rectified immediately,
  • shutdown the source device or disconnect it from the input terminal.
  • If the error state persists for a longer period of time, the terminal-internal current limitation reduces the signal current drawn for thermal reasons, even below 20 mA depending on the ambient conditions.
