80-250V SSR-80AA Solid State Relay 125KHz Android Phone MicroUSB RFID Reader Adjust the adjustable resistor to80 250V SSR 80AA Solid State Relay 80 250V SSR 80AA Solid State Relay This is AC To AC SSR 25AA Solid State Relay Module 80 250VAC 24 380VAC 25A. A solid state relay (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts. 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 which is isolated optically from the load. The
