Datasheet
## **Solid State Relays Industrial, 1-Phase ZS w. LED Types RS 23 A, RS 40 A** - **Zero switching AC Solid State Relay** - **Direct copper bonding (DCB) technology** - **LED indication** - **Clip-on IP 20 protection cover** - **Self-lifting terminals** - **Housing free of moulding mass** - **Fixed AC control input** - **Operational ratings up to 40 AACrms and 400 VAC** - **Blocking voltage: Up to 850 Vp** - **Opto-isolation: > 4000 VACrms** ## **Product De scri tion p** the status of the control input. The clip-on cover is securing touch protection (IP 20). Output terminals can handle cables up to 16 mm[2] . The zero switching relay is an inexpensive solution for resistive loads. The zero switching relay switches ON when the sinusoidal curve crosses zero and switches OFF when the current crosses zero.
