2 phase half wave rectifier solid state relay GZ21 GZ22


  • The low-voltage part and the high-voltage part are optically isolated.
  • The control signal is compatible with TTL logic interface.
  • The high-voltage control switch uses a power semiconductor thyristor.
  • A light-emitting diode (LED) indicates the operational status.
  • Widely used in electrolysis, electroplating, electromagnetic vibration, electromagnetic iron absorption, and other equipment for contactless switch control.
