1-Channel Solid-State Relay is some what similar to that of a mechanical relay & the difference is that, there is no moving contact in a Solid-State Relay. Here we make use of Phototrriac coupler to turn it ON and OFF. It finds its application in AC circuits as a TRIAC has got only limited aplications in DC.

Solid state relays do have several advantages over mechanical relays. One such advantage is that they can be switched by a much lower voltage and at a much lower current than most mechanical relays. Also, because there’s no moving contacts, solid state relays can be switched much faster and for much longer periods without wearing out.

    • Q
    • On the input side there are three terminal DC+, DC-, and CH1. As per my understanding, DC+ --_ 5 V and DC- --_ GND. What is the use of CH1?
