Feature

2 phase AC switching solid state relays

Optical isolation between input and output circuits.
Control signal with TTL logic interface.
LED indicator for working status.
Two sets of contactless switches, zero voltage turn-on, zero current turn-off.
Epoxy resin encapsulation, shockproof and corrosion-resistant, reliable operation.
Mainly used for computer and digital program-controlled interfaces and industrial automation control. Suitable for equipment such as industrial electric furnaces, electric ovens, motors, solenoid valves, and power switches.
