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.
