Dual output solid state relay (GDZ022)

  • Optomagnetic coupling isolation between input and output circuits.
  • Control signal compatible with PLC and TTL logic interfaces.
  • LED indicator for working status.
  • The L.Z series includes under-voltage protection, transient voltage absorption, and overcurrent short-circuit protection features.
  • Dual-channel normally open solid-state contactless outputs, which switch without sparks or arcing.
  • Encapsulated in epoxy resin, providing corrosion resistance and shock resistance, ensuring stable and reliable switch operation.
  • The product is primarily used for multi-channel control of DC power equipment, such as DC heaters, solenoid valves, motors, and charging/discharging equipment for new energy sources.
