Carlo Gavazzi RP1B40D5 single-pole PCB-mount solid state relay with instant-on switching, 5 A AC-51 rating, 12–440 V AC operating voltage and 4–32 V DC control input.
£19.31
The Carlo Gavazzi RP1B40D5 is a compact single-pole PCB-mount solid state relay (SSR) designed for reliable switching of AC loads in industrial automation and control systems. As part of the established Carlo Gavazzi RP1B solid state relay series, it provides instant-on switching, a 4–32 V DC control input and semiconductor output switching in a compact PCB-mount package.
The relay uses solid state switching rather than mechanical contacts, providing quiet operation and eliminating mechanical contact wear. Its instant-on switching operation allows the output to respond directly to the applied control signal rather than waiting for an AC zero crossing, making it suitable for applications where rapid switching response is required.
With a rated operational current of 5 A AC-51, an operating voltage range of 12–440 V AC and a 4–32 V DC control input, the RP1B40D5 is suitable for compact industrial switching applications. The relay provides an 850 Vp blocking voltage and uses soldering pins for direct PCB integration.
Solid state relays such as the Carlo Gavazzi RP1B40D5 use semiconductor technology instead of mechanical contacts to control AC loads. This provides silent operation and avoids mechanical contact wear, making the technology well suited to applications requiring dependable switching over repeated operating cycles.
The RP1B40D5 uses instant-on switching, allowing the output semiconductor to respond directly to the applied DC control signal rather than waiting for an AC zero crossing. Its 4–32 V DC control range provides compatibility with a variety of PLC and electronic control outputs, while the PCB-mount format allows integration into compact electronic assemblies.
