Control Relay

Control relays isolate a control circuit from what it switches, letting a low-power signal command a separate circuit while keeping the two electrically apart. Panel builders drop one in when a controller output cannot drive a load directly, when a failed relay has left an output stuck, or when a circuit needs its contacts multiplied so one signal can switch several things at once.

 

As an authorized electrical distributor for multiple manufacturers, we stock control relays from ABB, Carlo Gavazzi and more across competing lines, in a range of base types, body materials and amperage ratings, so you can match the base and socket a panel already carries, compare base types and analog outputs across brands, and keep a controller output clear of the load.
