The RH2B-UD-DC12V is a DPDT miniature power relay from the RH series, designed for high-capacity switching in a compact form factor. It operates with a 12V DC coil that has a rated current of 75 mA and consumes approximately 0.9W of power. This model includes an internal diode to absorb coil back-EMF, resulting in a maximum release time of 40ms, and features silver cadmium oxide contacts rated for 10A. It is designed to operate reliably in temperatures from -25°C to +40°C and has an electrical life of at least 500,000 operations at 120V AC, 10A. The relay's robust specifications make it ideal for various control circuits, automation systems, and power switching applications.
