Functional Devices RIBHX24BF Switch
The Functional Devices RIBHX24BF is a professional-grade enclosed relay and current sensor combination engineered for seamless integration into building automation systems and HVACR applications. This 20 Amp SPST-N/O relay features an internal fixed AC current sensor with a 0.25 to 20 Amp sensing range, allowing technicians to verify motor status or load performance without installing separate components. The unit operates on a 24 Vac/dc coil, drawing minimal current while providing reliable switching for resistive, ballast, and motor loads up to 2 HP at 277 Vac. Designed with a NEMA 1 plenum-rated housing, the RIBHX24BF includes a 1/2" NPT nipple for quick mounting to standard electrical knockouts. Integrated LED indicators provide instant visual feedback: a red LED signals relay activation, while a pink LED confirms that the current has exceeded the 0.25 Amp fixed trip point. This pre-wired RIB relay eliminates the need for external current rings, reducing labor time and ensuring a compact, clean installation for contractors.
Key Benefits- Integrated Design: Combines a power relay and current switch in a single housing, reducing wiring complexity and enclosure space requirements.
- High Load Capacity: Rated for 20 Amp resistive and heavy-duty motor loads, making it suitable for direct control of fans, pumps, and lighting circuits.
- Versatile Coil Input: The 24 Vac/dc input allows for compatibility with most standard HVAC control transformers and DC power supplies.
- Contractor Friendly: Pre-wired with 16-inch, 600V rated leads and color-coded for fast, error-free termination in the field.
- Reliable Monitoring: Small 0.25 Amp fixed threshold enables the detection of even small fractional horsepower motor operations.
Does this unit require an external current transformer (CT)?
No, the Functional Devices RIBHX24BF features an internal current sensor. The load wire simply passes through the internal sensing ring, eliminating the need for external CTs or additional mounting hardware.
Is this relay suitable for used in return air plenums?
Yes, the housing is UL listed and plenum-rated, meeting standard safety requirements for installation within environmental air spaces.
What do the different LED colors indicate during operation?
The red LED indicates the 24V coil is energized and the relay contacts are closed. The pink LED indicates the current sensor has detected a load of at least 0.25 Amps flowing through the monitored circuit.
