4.6 Inputs
Within the operating voltage range, all inputs are voltage-proof and overcurrent
protected. Alternatively, the analog inputs can also be used as digital inputs (DI).
The JXM-IO-E32 has 8 separate VEXT_SEN pins and 2 separate VREF_10 pins
that should be used to power the sensors. Each sensor supply is output via a
PTC thermistor so that a voltage dip caused by a short circuit can be detected.
VREF_10V supplies a stabilized 10 V voltage, while VEXT_SEN outputs the bat-
tery voltage.
