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
