4.7 Inputs
Within the operating voltage range, all inputs are voltage-proof and overcurrent
protected. The JXM-IO-E30 has 3 separate VEXT_SEN connector pins which
should be used to supply the sensors. The connector pins output the battery volt-
age via a PTC thermistor. The output voltage can be read back in the device so
that a failure of the sensor supply can be detected.
Alternatively, the analog inputs can also be used as digital inputs (DI_PNP).

Behavior in case of over-
current detection
In case of overcurrent, the current measurement is
interrupted. At the end of the overcurrent event, the
current measurement is automatically resumed.
