*) Constant and peak value
 | Overcurrent protection of the 20 mA inputs The current inputs are protected against damage by overcurrent by an internal current limitation, currents > 30mA may occur. In the event of a fault, the current limiter must not be overloaded by a voltage > 30V 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. |
