IDEC RH2B-UDC24V Relay

The IDEC RH2B-UDC24V is a heavy-duty DPDT relay engineered for versatile industrial applications and HVACR control circuits. Operating on a 24VDC coil, this RH series compact power relay handles a 10A contact rating, making it a reliable choice for switching resistive loads or inductive motor starters. It features standard blade terminals (plug-in type), which facilitate rapid installation or replacement in high-density panels using SH2B-05 or SH2B-05C sockets. The midget power relay design integrates a silver cadmium oxide contact material to minimize arcing and ensure long-term mechanical stability in demanding environments. Technicians often specify the RH2B-UDC24V for control panel troubleshooting due to its small footprint and high switching capacity. Whether you are managing solenoid valves or pneumatic actuators, this IDEC 2-pole relay provides the rugged durability required for continuous duty cycles without compromising space efficiency.

• High Switching Capacity: Manages up to 10A in a compact DPDT configuration, ideal for space-constrained enclosures.
• Standardized Fit: Utilizes 0.187-inch blade terminals for compatibility with industry-standard relay sockets.
• DC Coil Efficiency: The 24VDC coil voltage is optimized for most modern PLC and HVAC control systems.
• Durable Construction: Built to withstand vibration and mechanical shock common in industrial mechanical rooms.

What is the contact material for the RH2B-UDC24V?
This model utilizes silver cadmium oxide contacts, providing excellent resistance to welding and electrical erosion under 10A loads.

Can this relay be DIN-rail mounted?
Yes, when paired with an SH2B series socket, the relay can be easily snapped onto standard 35mm DIN rail for organized cabinet wiring.

How do I verify the coil polarity?
Since this is a DC coil relay, the internal wiring usually requires specific polarity; always refer to the terminal map on the transparent housing before energizing the circuit.
