What is Solid State Relay?
SSR is new type of excellent performance non-contact electronic switch device which using advanced foreign technology and equipment.
The input end only requires a small control current, and better compatibility with TTL, HTL, CMOS integrated circuit. And the output circuit adopts thyristor or high power transistor to connect and disconnect the load current. The input and output connecting with photocoupling, on –off without contact member, therefore it has lot of superiority, such as reliable, ast, no noise, long life, small volume, no spark, corrosion proof and anti vibration etc.
At present, SSR has been widely used in computer peripheral equipment, electric heating thermostat, CNC machine, remote control system, industrial automation equipment, signal lamps, relay family(EMR).
