Dry and wet contact

Could someone please clarify me what are dry and wet contacts used in GV-Net/IO Card.

Any outputs will be very much appreciated.

Wet contacts are tied to a output voltage, ie they turn things on and off, you wire contact to a voltage, and it switches that voltage on/off to whatever is connected to the other end of the relay.

 

Dry contacts just turn on / off or changeover, whatever the relay is designed to do, they are not wired to supply a voltage, and are the ones that you would normally wire a sensor to. They short or unshort whatever is connected to them.

 

If in doubt on relay contacts or wiring, contact a electrician before doing any high voltage work using them.

dry contacts are for indoor use only
