Normal close AC switching Solid State Relays (NC AC SSR relays)
NC AC SSR relays
Optical isolation between input and output circuits.
Control signal and TTL logic interface.
The normally closed contact is a semiconductor switching device.
No spark, no sound and no loss when the switch is switched frequently.
Epoxy resin encapsulation, anti-seismic and anti-corrosion, reliable work.
The products are mainly used for computer and digital program control interface and industrial automation control. Such as industrial electric furnace, electric oven, motor, power switch and other equipment.

1NO+1NC AC load solid state relays
Optical isolation between input and output circuits.
Control signal and TTL logic interface or 220VAC control.
Both normally open and normally closed points are thyristor non-contact outputs.
GT13KB-B can directly replace 220V voltage electromagnetic relay.
Epoxy resin encapsulation, anti-seismic and anti-corrosion, reliable work.
Products are mainly used for computer and digital program control interface and industrial automation control. Such as industrial electric furnace, electric oven, motor, power switch and other equipment.
