Save energy with bistable relays


Bistable relays  

Switch in an energy-saving manner with bistable relays

Phoenix Contact is now offering bistable relays again from the ST and EMG series. These are ideally suited to ecologically sustainable applications in machine building and systems manufacturing.

Bistable relays are able to adopt two stable switching states with zero current. In contrast to SPDT relays, a brief control pulse is sufficient to change the switching state. Since a continuous control voltage is not required, no power is dissipated through permanent heat generation. It is for this reason that stand-by losses are prevented. Applications can therefore be switched with bistable relays in a reliable and energy-saving manner.
