Features: 1. Can be well compatible with integrated circuits such as TTL and HTL CMOS 2. The output loop uses a thyristor or high power transistor to turn the load current on and off. 3. Optocoupler is used between input and output, there is no movable contact part, and it works reliable 4. Fast switching speed, no noise and long life, it has no spark, corrosion, anti-dry and anti-vibration, etc. 5. Widely used in computer peripheral interface equipment, electric furnace heating thermostat equipment; CNC mechanical remote control system, industrial automation equipment; signal lights, traffic lights, lighting stage control equipment; instrumentation copiers.
