This page brings together the 4 Channel Solid State Relay SSR Module pinout and key specifications, with the full datasheet PDF to preview below or download.

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 photometric sealed up into a little box.

Compares with the traditional mechanical relay, the Solid State Relay (SSR) has many advantages: it has a longer life, with a much higher turn-on/off speed and no noise. Besides, it also has better resistance to vibration and mechanical shock and better moisture-proof performance. This Solid State Relay Module is based on Omron G3MB, to control current up to 2A@240VAC, and can be widely used in various areas such as computer peripheral interfaces, temperature/speed light adjustment, servo control, petrochemical, medical instrumentations, financial devices, coal, meters, traffic signals, etc.
