Carlo Gavazzi RP1B23D3M1 solid state relay, a 3 A DIN rail mount instant-on switching relay designed for industrial AC load control applications.
£40.36
The Carlo Gavazzi RP1B23D3M1 is a compact and reliable DIN rail mount solid state relay (SSR) designed for efficient switching of AC loads in industrial automation and electronic control systems. As part of the advanced Carlo Gavazzi RP1B solid state relay series, it provides a dependable interface between low-voltage DC control signals and AC power circuits, making it suitable for machine control, OEM equipment and industrial switching applications.
This solid state relay uses instant-on switching technology to provide rapid response for applications requiring immediate AC load switching. The RP1B23D3M1 combines a PCB mount SSR with a DIN rail adaptor and LED indication, providing straightforward installation, visual status monitoring and reliable solid state switching performance.
With a rated load current of 3 A AC, an operating voltage range of 12–265 V AC and a 5–34 V DC control input, the RP1B23D3M1 is designed for switching AC loads in industrial control panels, automation equipment and electrical assemblies.
Solid state relays such as the Carlo Gavazzi RP1B23D3M1 provide electronic switching between control systems and power loads without mechanical contacts. This enables silent operation, fast switching response and improved reliability in industrial environments.
The RP1B series is designed for automation engineers, machine builders and equipment manufacturers requiring compact switching solutions. The DIN rail adaptor allows simple installation inside control cabinets while maintaining the benefits of PCB-based solid state relay technology.
