Introduction

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 phototriac sealed up into a little box. Solid state relays, 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.

IN8: CH8 Signal triggering end of 8-channel relay module (active at high level)

What is high level and low level?
Triggered at high level: when a forward voltage exists between signal triggering terminal (IN) and negative supply voltage. It generally connects positive supply voltage and triggering terminal together. When triggering terminal has positive supply voltage or reaches triggering voltage, the relay will close.
Triggered at low level: when the voltage between the signal triggering terminal and negative supply voltage is 0V, or the voltage at the triggering terminal is lower than positive supply voltage. If it lowers to a triggering voltage, the relay will close. It generally connects negative supply voltage and triggering terminal together.

Parameters:

Output Rating (Under 25℃ environmental temperature)

Note:

You should use matched DC power to supply electricity for the module.
