Solid State Relays

Solid Sate Relays have many names such as: SCR’s, Silicon Rectifiers, Thyristors, Zero Cross Relays and Triac Relays. They all mean the same thing, a non-contact AC switching relay.

Contactors are mechanical devices. After many cycles or use, mechanical devices finally wear out and no longer work. Mercury relays were a great solution in the contactor era. Mercury relays would clean their contacts and last very long periods of time. However anyone who’s ever used mercury relays in a high current or long use knows the consequences of a failed relay. Mercury all over the place! Solid state relays are a great solution for both replacing mercury relays and many contactor applications.

The Watlow family of Din-A-Mites and Power Series SCR’s can fit any heating system requirement. The Idec zero cross relays are a great low cost solid state solution.
