Product Details

Crydom Series 1 Solid State Relays

Crydom Series 1 range of solid state relays offer a wide range of ratings from 10 A to 125 A at 24 V ac to 280 V ac. Crydom has incorporated many features within this particular range of panel mount solid state relays including AC or DC control and SCR output for heavy industrial loads. Both zero-crossing (resistive loads) and random-fire (inductive loads) output versions are available.
