Functional Devices RIB RIBXGHTA Sensor

The Functional Devices RIBXGHTA is a high-performance, enclosed split-core AC sensor engineered for precise current monitoring in demanding HVACR and building automation environments. Designed as a solid-state SPST single pole single throw current switch, this unit features an adjustable trip point from 0.75 to 150 Amps, allowing technicians to fine-tune sensitivity for diverse motor loads and equipment statuses. Operating on a 120V switching voltage, the RIBXGHTA sensor utilizes a hinged split-core design that enables non-invasive installation without disconnecting the primary conductor, significantly reducing field labor time. The integrated terminal strip accepts 14-22 AWG wire, providing a secure landing point for control circuit leads. With a maximum sense voltage of 600 Vac and a rugged enclosure rated for temperatures between -30 and 140° F, this adjustable current sensor is a reliable choice for monitoring fans, pumps, and cooling tower motors where real-time proof of flow or belt-loss detection is critical for system interlocks.

• Split-core architecture allows for retrofitting around existing wiring without interrupting power to the load.
• Adjustable trip threshold (0.75-150A) provides flexibility to detect small current changes or large motor failures.
• Onboard LED indicators offer immediate visual confirmation of current status and unit power for faster troubleshooting.
• Solid-state SPST contact ensures a bounce-free switching signal compatible with most DDC and PLC controllers.
• UL Listed and CE compliant design meets stringent safety standards for commercial and industrial installations.

How do I set the trip point on the RIBXGHTA?
With the monitored motor running at normal load, slowly turn the adjustment potentiometer until the status LED changes state. We recommend setting the threshold slightly below the typical operating amperage to ensure the internal SPST contact remains closed during standard operation but opens if current drops due to a mechanical failure.

Can this sensor be used for 4-20mA feedback?
No, the RIBXGHTA is a binary current switch, not a transducer. It provides a simple open/closed status based on the adjustable setpoint. If your application requires a continuous proportional signal, you would need a current transducer from the RIBXG series with a 0-5V or 4-20mA output.

What is the maximum voltage the sensor can clamp onto?
The internal current transformer is rated for a maximum sense voltage of 600 Vac. However, ensure the secondary switching circuit does not exceed the 120 Vac limit specified for the RIBXGHTA contact rating.
