Volt Free Contact
Volt Free Contact
(OP)
Does remote start/stop of equipment is possible through volt free (Dry) contacts provided in equipments' control panel? I want to start/stop the pump through BMS. Manufacturer states that he has provided Volt free contacts for start/stop in pump's control panel.

But our engineer says, volt free contacts are for taking status only. You cant provide command via volt free contacts. Any advise pls.

RE: Volt Free Contact
As noted above you need to know what the contacts need in order to make the contact - 12VDc or 240V AC or something else and maximum current the contacts can take.
Simply saying there are a pair of contacts here which start / stop the pump without giving you the voltage and current rating is next to useless.
Also is the relay latched or does the pump stop on loss of volts?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
