Functional Devices RIBX24BF Sensor Relay

The Functional Devices RIBX24BF is a versatile enclosed relay and current sensor combination designed for high-performance power monitoring and control applications. This unified solution features a 20 Amp SPDT relay and an internal fixed current switch, allowing for simultaneous motor control and status feedback without the need for external current rings or additional mounting hardware. Engineered with a 24 VAC/VDC coil, the Functional Devices RIBX24BF operates reliably across a sensing range of 0.5 to 20 Amps, making it ideal for verifying fan or pump operation in building automation systems. The NEMA 1 rated, plenum-rated housing ensures code compliance for installation in ceiling spaces, while the 16-inch 600V rated lead wires simplify wiring in crowded electrical panels. This current sensing relay supports heavy electrical loads, including resistive, ballast, and tungsten ratings, and features high- and low-voltage separation within a single compact junction box for maximum field safety.

• Integrated Design: Combines a 20 Amp SPDT control relay and a fixed current sensor into one pre-wired RIB relay housing, reducing installation time and material costs.
• Enhanced Reliability: Features an expected mechanical life of 10 million cycles and an LED indicator for instant visual confirmation of relay status.
• Flexible Applications: Rated for up to 2 HP at 277 VAC, making it suitable for managing large inductive motor loads and lighting control.
• Durable Construction: The NEMA 1 enclosed relay is UL listed for Energy Management (UL 916) and Fire (UL 864) applications, functioning in temperatures from -30°F to 140°F.

Is an external current transformer needed for the RIBX24BF?
No, the Functional Devices RIBX24BF utilizes an internal fixed AC sensor, allowing the load wire to pass directly through the device for streamlined monitoring.

What is the trip point for the current switch?
This model features a fixed threshold set at 0.5 Amps. The sensor will signal the status once the current exceeds this minimum value.

Can this relay be used in plenum spaces?
Yes, the RIBX24BF is housed in a plenum-rated enclosure, meeting the necessary requirements for installation in air-handling spaces.
