GDZ09 DC solid state relay


  • Electromagnetic optocoupler isolation between input and output circuits.
  • Control signal compatible with PLC, TTL, PWM logic interfaces.
  • LED indicator for working status.
  • Built-in input under-voltage protection and output transient over-voltage absorption protection.
  • Solid-state, contactless output with fast switching speed, no sparks or arcing.
  • Encapsulated in epoxy resin, providing corrosion and shock resistance, ensuring stable and reliable switch operation.
  • The product is mainly used for controlling high-power DC power supply equipment such as PTC DC heaters, new energy conversion, battery charging and discharging, capacitors, etc.
