Functional Devices RIBXLCRF Sensor Relay

The Functional Devices RIBXLCRF is a robust current sensing relay designed for reliable load monitoring in commercial HVAC and building automation systems. Supporting a 10 Amp SPDT output, this device functions as a precise current switch that eliminates the need for separate current transducers and external power supplies for the sensor. It features a fixed threshold of 0.50 Amps, making it ideal for detecting belt breaks, motor failure, or proof of flow in high-demand environments. Engineered with a large coil diameter to accommodate heavy-gauge wiring, the RIBXLCRF current relay provides seamless integration into BAS controllers and mechanical systems. The solid-core design ensures accurate induction across the sensing circuit, while the dry contact output provides versatile control for auxiliary equipment. This unit effectively replaces the FUN-RIBXL-CRF, maintaining the same form factor and technical specifications required for field replacements and new installations.

• Pre-calibrated Threshold: Fixed 0.50 Amp trip point ensures reliable "on/off" status monitoring without field adjustment.
• Integrated Relay: Combines a current sensor and a 10 Amp SPDT relay into one housing, reducing enclosure space and wiring complexity.
• High Load Capacity: Rated for up to 10 Amps at 277 Vac, suitable for direct control of small motors and signaling circuits.
• Solid Core Design: Provides a stable and durable sensing ring that handles high-vibration HVAC environments.
• LED Indicators: Onboard status LEDs provide immediate visual confirmation of relay activation and current detection.

What is the minimum current required to trip the relay?
The Functional Devices RIBXLCRF has a fixed trip point of 0.50 Amps; any current detected above this threshold will energize the internal relay.

Can this relay be used for proof-of-flow on VFDs?
Yes, this current sensing switch is frequently used to monitor the high side of a VFD to confirm motor operation, though it is optimized for 60Hz applications.

Does it require an external power supply?
The current sensing portion is self-powered via induction from the monitored line, while the relay coil requires the standard control voltage specified in the wiring diagram.
