Product Details

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.
