Single Phase Solid State Relay 250V SSR-50DA 50A DC Control AC
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.

Description
Single Phase Solid State Relay 250V SSR-50DA 50A DC Control AC
The DC- To- DC SSR-50DD Solid State Relay Module (SSR) is an electronic switch that contains no moving parts, unlike an electromechanical relay. The types of SSR are photo-coupled SSR, transformer-coupled SSR, and hybrid SSR. A photo-coupled SSR is controlled by a low-voltage signal 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.
