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.
