Description

The zero switching Carlo Gavazzi RS1A series solid state relay with alternistor output is an inexpensive solution for resistive loads. The Carlo Gavazzi RS1A series solid state relays' zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero. With an LED to indicate the status of the control input, the Carlo Gavazzi RS1A series solid state relays' clip-on cover is securing touch protection (IP 20). Output terminals can handle cables up to 16 mm2.
