How to wire the Solid State Relay?

Solid state relays (SSR) are electronic switches that use power electronic devices as switching components, with many advantages over traditional electromagnetic relays (EMR). There are many types of solid state relays, and our solid state relays are roughly divided into DC solid state relays, AC solid state relays, industrial solid state relays, and PCB mounting solid state relays. Of course, it is important to confirm whether the specifications meet your requirements before installing and using our solid state relays, such as input current, input voltage, output current, and output voltage. Through this article you will learn the circuit wiring diagrams of our solid state relays.
