1. PCB Type AC Solid State Relay is called “SSR” for short. This products made by our factory is the latest non-contact electronic switch device with good ON-OFF performance.
2. Its input end only requires tinny control current and can be compatible with integrated circuit of TT land CMOS, etc. The output return circuit adopts two way controlled silicon or big powder transistors to cut on or cut off the loading current.
3. The photoelectric coupler is adopted between the input and output.
Features and Uses
1. Because solid state relay is a non-contact switch element made up of solid state elements. Compared with electromagnetic relay, it is more reliable. It has series advantages, such as long service life, little disturbance to surrounding and strong anti-interference performance,etc.
2. It has wide application fields, like input/output interface of computer and program control, electric stove heating constant temperature equipment, digital control machine, remote control system, industrial automatic device, signal lamp, traffic lamp, stage lighting control equipment, instrument and meter, medical equipment , duplicator, color enlarger, and rubber & plastic machine,etc.
3. In some special devices which require damp proof, fireproof and anti-corrosion , and under bad working environment , SSR has incomparable superiority in comparison with tradition electromagnetic relay.
