Functional Devices RIBXGTA Sensor

The Functional Devices RIBXGTA is a solid-state adjustable current sensor designed for accurate monitoring of AC loads in commercial HVACR and building automation systems. Built with a split core housing, this sensor facilitates easy installation around existing conductors without requiring wire disconnection, making it an essential component for retrofitting fan status monitoring or pump flow detection. It operates by detecting the magnetic field around a conductor and closing a solid-state N.O. contact when the current exceeds the user-defined threshold. The adjustable trip point spans from 0.75 to 150 Amps, allowing technicians to fine-tune sensitivity to differentiate between a broken belt and a functional motor under load.

Engineered for high-demand environments, the RIBXGTA current transducer handles up to 30 VAC/DC at 0.4 Amps on the output side, ensuring compatibility with most DDC controllers and PLCs. The integrated LED indicator provides immediate visual feedback on the contact status, streamlining the commissioning process and troubleshooting on the job site. Its compact, self-powered design eliminates the need for an external power supply, reducing wiring complexity and potential failure points within the electrical cabinet.

Key Benefits

• Split core design allows for rapid installation on active circuits without interrupting power.
• Adjustable setpoint provides a versatile range of 0.75A to 150A for precise load monitoring.
• Self-powered operation draws induction from the monitored line, simplifying field wiring.
• Solid-state output provides a reliable N.O. switch for interfacing with building management systems.
• Onboard LED status offers real-time diagnostics for verification of load threshold crossing.

Common Questions

How do I calibrate the trip point for a motor status application?
With the motor running at normal load, turn the adjustment potentiometer until the LED illuminates, then adjust slightly further to ensure a stable signal that can account for minor voltage fluctuations.

Can the RIBXGTA be used to sense undercurrent conditions?
Yes, by setting the threshold just below the normal operating amperage, the sensor can detect a drop in current—such as a snapped belt or coupling failure—causing the contact to open.

Is this sensor compatible with Variable Frequency Drives (VFDs)?
While it can monitor loads controlled by a VFD, it is best practice to install the sensor on the line side of the drive or ensure the drive is operating within standard frequency ranges for accurate induction.
