Solid State Relay Interface Applications.

Controlling outputs from programmable controllers, positioning controllers plus other devices are transferred to actuators whilst providing isolation. The G3M is suitable for applications that require frequent switching, noiseless operation and resistance to vibration, shock, dust and gas.

What does Zero Cross Function mean in SSR in Solid State Relays?

Zero cross function will allow the relay to turn ON when the AC load power supply approaches 0 V suppressing any noise generated with a sudden load current increase. Zero cross function is effective across 2 types of noise, noise on power lines and noise emitted into open space.
