Functional Devices RIBH1C Relay

The Functional Devices RIBH1C Relay is a heavy-duty enclosed pilot relay engineered for building automation and HVAC industrial control circuits. This SPDT (Single Pole Double Throw) relay features a unique dual-coil input design, capable of accepting 10-30VAC/DC or 208-277VAC, making it a versatile "Relay in a Box" for multi-voltage field applications. With a 10 Amp resistive contact rating, the RIBH1C is designed to handle pilot duty, ballast control, and motor loads up to 1/3 HP. The unit is housed in a NEMA 1 rated plenum enclosure and includes an external LED indicator to provide real-time status of the relay coil activation. Professional installers prefer the RIBH1C for its pre-wired 16-inch leads and 1/2" NPT nipple, which streamline installation into standard electrical knockouts for equipment like air handlers, rooftop units, and lighting arrays.

• Universal Compatibility: The multi-voltage coil operates on 24V control circuits or high-voltage 208-277V systems without external transformers.
• Contractor-Ready Design: Pre-wired with 600V rated color-coded leads to ensure rapid, error-free wiring in the field.
• Space-Saving Enclosure: The compact, plenum-rated housing allows for mounting inside or outside of ductwork and electrical panels.
• High Cycle Life: Features a mechanical life expectancy of 10 million cycles for long-term reliability in demanding HVAC/R control applications.
• Visual Diagnostics: Integrated LED status indicator allows for immediate troubleshooting of the control signal.

Can the RIBH1C be used for motor loads?
Yes, this 10A SPDT relay is rated for 1/3 HP at 120-240VAC (Normally Open) and 1/4 HP at 277VAC, making it suitable for fan motors and small pumps.

What is the difference between the RIBU1C and the RIBH1C?
The primary difference is the high-voltage coil input: the RIBU1C accepts 120VAC, whereas the RIBH1C is specifically designed for 208-277VAC high-voltage environments.

Is the housing suitable for outdoor use?
The standard RIBH1C features a NEMA 1 enclosure intended for indoor or plenum-rated applications. For wet environments, look for the NEMA 4X version of this relay.
