Functional Devices RIBXLCRA Sensor Relay

The Functional Devices RIBXLCRA is a robust, technician-grade 10-30VAC/DC SPDT current sensor relay designed for seamless integration into building automation systems (BAS) and industrial motor control applications. This unit effectively replaces the FUN-RIBXL-CRA, offering an enclosed, pre-wired solution that simplifies field installation. Featuring a solid-core current switch with a 1.25-150 Amp sensing range, the RIBXLCRA allows for precise monitoring while providing a 10 Amp rated relay contact. The adjustable trip point and dual LED indicators—one for relay activation and one for current threshold status—enable rapid onsite diagnostics. Built with high-voltage and low-voltage separation within a NEMA 1 enclosure, this professional-grade component ensures clean wiring and compliance with UL 916 and UL 864 standards. Its 16-inch 600V rated leads and 50/60 Hz frequency compatibility make it a versatile choice for HVACR contractors managing complex electrical loads, pumps, and fans where precision current sensing and reliability are non-negotiable.

• Versatile Control: Features a 10-30VAC/DC coil rating, making it compatible with a wide range of low-voltage control circuits.
• Dual Functionality: Combines a control relay and an adjustable solid-core AC sensor in a single, compact junction box to reduce enclosure footprint.
• Field Serviceability: Integrated LED indicators provide immediate visual feedback on relay state and current status, streamlining troubleshooting.
• Enhanced Safety: Internal separation between high and low voltage sections ensures safe handling and long-term circuit integrity.
• Plenum Rated: Suitable for use in environmental air spaces, meeting stringent building code requirements for commercial HVAC installs.

What is the primary application for the RIBXLCRA?
This device is typically used for motor status feedback and load control. It allows a controller to drive a motor while simultaneously confirming the motor is drawing current, confirming the belt or drive is intact.

How do I adjust the current trip point?
The unit features an onboard potentiometer. Adjust this screw to set the adjustable threshold between 1.25 and 150 Amps to match the specific operational load of your equipment.

Does this unit require an external power source for the sensor?
No. The current sensor is self-powered from the induced current of the monitored line. Only the relay coil requires 10-30VAC/DC for activation.
