Functional Devices RIBXG21TA AC Sensor
The Functional Devices RIBXG21TA AC Sensor is a professional-grade split-core current switch designed for accurate load status monitoring in commercial HVACR systems. Built for heavy-duty field use, this adjustable current sensor handles a wide sensing range from 0.75 to 150 Amps, making it a versatile choice for monitoring fan motors, pumps, and other critical inductive loads. The split-core housing allows for easy installation around existing wiring without disconnecting the circuit, while the integrated wire clamp ensures a secure fit. With a switching voltage rating of 120-277 Vac and a solid-state SPST contact, the RIBXG21TA provides reliable digital feedback to building automation systems (BAS) or controllers. The unit features externally visible LEDs for immediate status indication during the calibration of the adjustable trip point, ensuring peak system performance and simplified commissioning for contractors on the job site.
Key Benefits- Split-core design allows for fast retrofitting and installation without breaking the electrical circuit.
- Adjustable trip point provides precise control for identifying belt loss, motor failure, or mechanical jams.
- Terminal strip termination supports clean field wiring and accepts 14-22 AWG wire sizes.
- Self-powered operation eliminates the need for an external power supply to the sensor.
- Plenum-rated housing meets strict safety requirements for installation in air handling spaces.
How do I set the trip point on the RIBXG21TA?
With the load running at normal capacity, adjust the threshold screw until the "Over Threshold" LED illuminates. It is recommended to turn the screw slightly further to provide a reliable operational differential.
Can this sensor be used with Variable Frequency Drives (VFDs)?
Yes, however, for best results on VFD applications, the sensor should be placed on the line side of the drive or at a point where the frequency is relatively stable to avoid nuisance tripping.
What is the purpose of the dual LEDs?
The LEDs provide immediate visual confirmation of the contact status: one indicates current is below the threshold (open), and the other confirms the current is above the set point (closed).
