Notes:
1. Open collectors can be pulled up to 30 V max and sink 50mA continuous.
2. Do not connect a 15 VDC and 24 VDC source to the unit at the same time, use one or the other.
3. GND signals to be used for analog feedback signals, i.e. twisted pair with I
out
4. Optional outputs for DC link voltage feedback
