Description

This is 2 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.
A?Solid State Relay is similar 2 Channel 5V Relay Module Solid State High-Level SSR DC Control 250V 2A with Resistive to a mechanic relay where it can be controlled through a digital signal.?Solid State Relay?generates no noise and has a much longer lifespan compared to the traditional?mechanic relay.
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 are no moving contacts,?solid-state relays?can be switched much faster and for much longer periods without wearing out.
Input Parts :
