This is the 24V variant of the 4 Channel 3-24V Relay Module Solid State Low Level SSR DC Control DC with Resistive Fuse in Relay Modules. Available at ₹562.86 (₹477.00 + GST) with free shipping across India.
This is 4 Channel 3-24V Solid State Relay Module. A solid-state relay (SSR) is just what it sounds like; an IC that acts like a mechanical relay. They allow you to control high-voltage AC loads from lower voltage DC control circuitry. They accomplish this by using infrared light as the ‘contact,’ a solid-state relay is really just an IR LED and a photo Triac sealed up into a little box. Solid-state relays have several advantages over mechanical relays.
When the input logic voltage is applied to the coil, the NC will disconnect from the COM breaking the conductivity between the two. At the same time, the NO will connect with the COM allowing conductivity between them. Depending on your wiring this will turn on or off the connected load.
