Solid state relay SSR (Solid state releys) is one kind passes without the electronic contact breaks the electronic switching, for four pole active device. Two 端子 for input control end, moreover the beginnings and ends are controlled for the output the end, middle uses the photoelectricity isolation, took between the input output the electrical isolation (floats spatially). Adds on direct current or the pulse signal when the input end, the out-port can from shut off the condition to transform Cheng Daotong the condition (does not have signal assumes blocks condition), thus controls 大负�? The entire component does not have may move the part and the electronic contact, may realize is equal to the commonly used mechanical type electromagnetic type relay same function.
Because the solid state relay is the non- electronic contact on-off element which is composed by the solid-state element, therefore compares with the electromagnetic type relay has the work reliably, the life long, foreign disturbance small, can with the logic circuit compatible, the antijamming ability strong, the shutter speed be quick and the easy to operate and so on a series of merits, thus has the very wide application domain, has potential of the gradually substitution tradition electromagnetic type relay, and may further expand to the tradition electromagnetic type relay is unable application domain and so on computer. At present the domestic sale tendency fiercest, the type is most complete, performance most outstanding first choice Switzerland CARLO GAVAZZI the production series SSR product.

The SSR solid state relay triggers the form, may divide into zero, has been stochastic, the peak value and the phase switch. Exerts appropriate control signal 4-32VDC or 20-280VAC when the input end, crosses zero, is stochastic the way which, peak value SSR acts according to immediately corresponds to lead passes. After the control signal cancellation, the load current is lower than the bidirectional silicon-controlled rectifier maintenance electric current (exchange commutation), SSR shuts off.
Crosses the zero SSR interior to include the zero examination electric circuit, when exerts the input signal, only has when the load supply voltage had achieved the zero zone time, SSR can lead passes, and has the possibility to create the power source for half cycle the biggest time delay; Stochastic is so long as has the signal control then may pass as necessary breaks. Phase switch, but because the load operating current approximate sine wave, the higher harmonic disturbs slightly, therefore the application is widespread.
SSR widely applies to each domain, uses in load control and so on preheater pipe, infra-red lamp tube, light, electrical machinery, magnetism valve. In pursue efficiency and the quality technical time, SSR certainly is various enterprises solution first choice product.
Switzerland good happy (Carlogavazzi) is the European famous automation brand, the headquarters is located in Switzerland, was established in 1936, by was solid, steady, the comprehensive development style enjoys a good reputation European and American 60 年载, provided goes against the level in the global scope the automated product and the technical support, and gradually obtained the Chinese automation user the approval and the praise.
