Three channel output dc solid state relay (GDZ033)

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