RP1A23D5 is a 1-phase AC solid state relay designed for PCB mounting, providing an ideal interface between logic controls and AC loads. It features zero-cross switching mode with a rated operational voltage of 230 VACrms, blocking voltage of 650 Vp, and rated operational current of 5 AACrms. The relay accepts a DC control voltage of 3 to 32 VDC with opto-isolation greater than 4000 VACrms for reliable signal isolation. Built with surface mount technology and flexible encapsulation for extended life, it operates within a temperature range of -20°C to +70°C. Common applications include switching heaters, motors, lights, valves, and solenoids in industrial control systems.
