Product Details
GDZ08 DC load 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.
