IDEC Relays RH2B-ULAC220-240V Relay
The IDEC RH2B-ULAC220-240V is a heavy-duty DPDT power relay designed for industrial HVACR control circuits and automation panels. Featuring a 10A switching capacity and blade terminals, this compact power relay fits the industry-standard RH series footprints, making it a reliable drop-in replacement for failed contactors or control logic components. The 220-240VAC coil is engineered for stable pull-in voltages in fluctuating power environments, while the built-in LED indicator provides immediate visual diagnostics for field technicians troubleshooting complex sequences. Its double-pole double-throw configuration allows for simultaneous control of independent loads, such as a compressor and a fan motor. Built with silver cadmium oxide contacts, the RH2B-ULAC220-240V resists welding and pitting under high-inrush inductive loads. Professional installers prefer this IDEC relay for its robust mechanical life and minimal heat dissipation in high-density DIN-rail mounted enclosures.
Key Benefits for Technicians- High Contact Rating: 10A DPDT contacts handle significant inductive and resistive loads without premature failure.
- Integrated Diagnostics: The illuminated indicator simplifies troubleshooting HVACR control circuits during commissioning.
- Standardized Fit: Standard blade terminal design ensures compatibility with common SH series relay sockets.
- Space-Efficient Design: Large switching capacity housed in a compact frame saves critical panel space in retrofit applications.
Can I use this relay for both 220V and 240V systems? Yes, the coil is rated for the 220-240VAC range, making it compatible with standard single-phase industrial power supplies.
What is the difference between the UL and non-UL versions? The 'UL' designation in the part number indicates the presence of the LED indicator and compliance with specific safety standards for the North American market.
How do I verify the contact configuration? This is a DPDT relay, meaning it provides two sets of changeover contacts, allowing for both normally open and normally closed logic paths.
