The RH1B-UDC48V is a compact power relay from the RH series, featuring a single pole double throw (SPDT) contact configuration and blade terminals. It operates with a 48V DC coil that has a nominal power consumption of 0.8W and a resistance of 2,660Ω. This model includes an integrated diode to absorb back-EMF, making it suitable for transistor-driven circuits, and has a release time of up to 40ms. The silver cadmium oxide contacts are rated for 10A, providing a large switching capacity in a miniature form factor for various control and power applications.
