IDEC Relays RH1B-ULAC24V Relay
The IDEC RH1B-ULAC24V Power Relay is a heavy-duty, single-pole double-throw (SPDT) switching solution designed for high-density HVACR control panels and industrial automation systems. As a core component of the IDEC RH Series, this compact 24VAC coil relay features silver cadmium oxide (AgCdO) contacts, which are specifically engineered to minimize voltage arcing and provide a robust 10A contact rating. The integrated LED indicator provides immediate visual diagnostics, allowing technicians to verify coil energization at a glance without a multimeter.
Designed for versatile installation, the RH1B-ULAC24V utilizes standard 0.187-inch blade terminals, facilitating quick-connect wiring or secure placement into DIN rail mount sockets. With a miniature "midget" footprint of just 14mm width, it maximizes rail space while delivering the switching capacity usually reserved for much larger general-purpose relays. Its high dielectric strength (2000VAC) and rapid 20ms response time ensure dependable performance for motor control, lighting circuits, and sequence control applications.
Key Benefits for Technicians
- Simplified Troubleshooting: The built-in LED operation indicator confirms the control circuit status instantly, reducing downtime during system maintenance.
- Space-Saving Design: The compact RH Series profile allows for higher component density in crowded electrical enclosures.
- High Load Capacity: Rated for 10 Amps, providing the reliability needed for inductive loads like small motors and solenoids.
- Arc Mitigation: Silver cadmium oxide contacts improve longevity by resisting contact welding and material transfer under load.
- Universal Mounting: Compatible with various relay sockets for DIN rail, surface, or panel mounting configurations.
Common Questions
Can I use this relay for DC switching?
Yes, the RH1B-ULAC24V is rated for up to 30VDC at 10A, making it suitable for both AC and DC load switching applications.
What is the difference between the RH1B and the RH2B?
The RH1B-ULAC24V is an SPDT (1-pole) relay. If your application requires switching two separate circuits simultaneously, you would need the DPDT (2-pole) RH2B model.
Does this model include a manual check button?
The suffix -UL indicates an LED indicator and blade terminals; it does not standardly include the manual check button found on the 'C' versions of the series.
