This is AC To AC SSR-25AA Solid State Relay Module 80-250VAC/24-380VAC 25A. A SSR (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts. The types of Solid State Relay are photo-coupled SSR, transformer-coupled SSR, and hybrid Solid State Relay. A photo-coupled SSR is controlled by a low voltage signal which is isolated optically from the load.

The control signal in a photo-coupled SSR typically energizes an LED which activates a photo-sensitive diode. The diode turns on a back-to-back thyristor, silicon-controlled rectifier, or MOSFET transistor to switch the load.

This particular SSR can switch current loads of up to 100A with an 80-250VAC input and a zero cross trigger control method. Each one of these relays is equipped with four screw terminals (for use with ring or fork connectors) and a plastic cover that slides over the top of the relay to protect the terminals.

Features:

1. Long service life and high reliability
2. Reduced electromagnetic interference
3. Highly reliable, compact size designed to offer users maximum simplicity.

Package Includes:

1 x80-250V SSR-25AA Solid State Relay

[vc_row][vc_column][vc_column_text]This is a 2 Channel 12V 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 Higher 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 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.

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.
