Damage may result!

The pins labeled "NC" must not be contacted.
Before installation and commissioning, please also read the chapters Installation of EJ modules and Commissioning!

	Current carrying capacity of the input contacts The maximum permitted current on the signal-relevant pins (inputs, GND) is 40 mA (if applicable).

	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.
