Why Choose the Carlo Gavazzi RP1B48D3 Solid State Relay?
The Carlo Gavazzi RP1B48D3 is a compact and reliable single-pole PCB-mount solid state relay (SSR) designed to provide an efficient interface between low-voltage DC control circuits and AC electrical loads. As part of the established Carlo Gavazzi RP1 series, it combines semiconductor switching technology with a space-saving PCB format suited to industrial automation, machine control and OEM electronic equipment.
This solid state relay features instant-on switching, allowing the output to activate rapidly when the control signal is applied. With no mechanical contacts to wear, the RP1B48D3 provides silent operation, dependable repetitive switching and long service life, making it particularly suitable for applications involving frequent switching of resistive and inductive AC loads.
With an operating voltage range of 12–530 V AC, an AC-51 rated current of 3 A and a 4–32 V DC control input, the RP1B48D3 provides a versatile interface between electronic controllers and mains-powered equipment. Its PCB mounting format and soldering-pin connections simplify integration into compact industrial and electronic control assemblies.
