Power supply to the ACE PLC is provided via a two position pluggable connector, included with the ACE unit.

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.

All digitals inputs/outputs are compatible from 5 to 28 VDC whatever the ACE
The HMIs can be powered from 10 to 28 VDC

We are working on updating all ACEs to make them compatible from 5 to 30 VDC. Contact us if you need more information.

From 07/2020, all ACEs are compatible with 5-24 VDC except 1630v5, 1700, 1701 which must be powered by 5 VDC. (We provide DC-DC converter for free)
