Power supply via USB or 2 position plug
Power supply to the ACE PLC is provided via a two position pluggable connector, included with the ACE unit.
All ACEs shipped today are compatible from 5 to 24 VDC.
The ACE can be powered on via:
- its USB port (except ACEs with analog outputs)
- or its 2 position pluggable connector
You can plug both (USB and Power plug) at the same time.
PLCs are reverse voltage protected.
Input power goes through a switching regulator to regulate to 5 VDC. Alternately, 5V from the USB passed through a diode to the same point. The 5V is then regulated to 3.3 V, which is what the internal circuitry runs on.
All digitals inputs/outputs are compatible from 5 to 28 VDC whatever the ACE
