EJ3114-0010 – connection 3:

Current carrying capacity of the input contacts

The maximum permitted current on the signal-relevant pins (inputs, GND) is 40 mA (if applicable).

EJ3114-0010 – connection 4:

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 module. If the error condition persists for a longer period of time, the internal module current limitation reduces the absorbed signal current for thermal reasons, depending on the ambient conditions also below 20 mA.
