Post Body

Has anyone ever seen a voltage monitoring relay, or even just relay with a DIN rail base with a 70v DC coil?

I have an application where we are running servo motors off a 70v power supply. The supply has no feedback to monitor. When the motors crash sometimes the supply faults. I want to be able to throw an alarm for this and power cycle it from the HMI.

I’ve seen some voltage transducers that would give me a 4-20ma signal but I would have to add an analog card to my rack. Was looking for something simpler to just toggle a discreet input.
