    UPS for PLC

    Thanks for the reply, I know that there are many ups available at the store, the problem is finding one that can be switched on/off externally. I do not want a computer to control the ups with a usb or serial port.

    UPS for PLC

    Can anyone recommend a ups for plc protection. (arround 350 VA) The unit must have the ability to turn off with an external switch/relay and provide a dry contact for power status. Thanks
