SDAS-01-7Y2S1024 Solid State Relay (SSR) is a contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, bidirectional thyristors, and other semiconductor devices) to achieve contactless and spark free connection and disconnection of the controlled circuit. Therefore, solid-state relays are also known as “contactless switches”. Solid state relays consist of three parts: input circuit, isolation (coupling), and output circuit. By using a small control signal at the input end, it is possible to directly drive a high current load. It is a four terminal active device, where two terminals are input control terminals and the other two terminals are output controlled terminals. Solid state relays have both amplification and driving functions, and are also suitable for driving high-power switch type actuators. Compared with electromagnetic relays, solid-state relays have the advantages of contactless, long lifespan, fast speed, low external interference, and high reliability. They have been widely used in various switchgear and automatic control devices. In addition, SDAS-01-7Y2S1024 solid-state relays can also be divided into two categories based on different usage scenarios: AC solid-state relays and DC solid-state relays; According to the working principle, it can be divided into two types: voltage type and current type; According to the working mode, it can be divided into two types: temperature compensation with positive temperature coefficient and non temperature compensation with negative temperature coefficient.
