Functional Devices RIBX24BA Relay

The Functional Devices RIBX24BA is a versatile enclosed power relay combined with a high-performance integrated current sensor, designed for demanding automation and control environments. This SPDT relay features a 24 VAC/DC coil and supports up to a 20 Amp resistive load, making it ideal for managing fractional horsepower motors, lighting circuits, and heavy-duty HVAC actuators. The critical advantage of the RIBX24BA is its split-core current sensing capability, which provides real-time feedback on motor operation or heater status without requiring additional mounting space. The sensor triggers at a 0.5 Amp threshold and handles up to 20 Amps, simplifying status monitoring for fans and pumps. Its NEMA 1 enclosure and pre-wired 16-inch leads allow for rapid installation directly to a standard electrical box or controller cabinet, ensuring reliable current sensing relay performance in both commercial and industrial retrofit applications.

• Integrated Current Sensor: Combines a 20A relay with a .5-20A sensor to reduce labor and enclosure footprint.
• Dual-Voltage Versatility: Operates on 24 VAC or 24 VDC control signals for broad system compatibility.
• Pre-Wired Housing: Features 16-inch color-coded leads to eliminate terminal landing errors in the field.
• External LEDs: Provides immediate visual confirmation of both relay coil status and current sensor closure.
• High Amperage Rating: Rated for 20 Amp inductive and resistive loads, capable of switching 1 HP motors at 120V.

How do you adjust the current sensor trip point on the RIBX24BA?
The current sensor in this model is fixed-threshold. It is designed to close its output contact when it detects at least 0.5 Amps passing through the monitored conductor, requiring no manual calibration.

Can the sensor monitor a different circuit than the one the relay is switching?
Yes, the current sensor and relay coil are electrically isolated. You can use the relay to switch one load while using the sensor to monitor the status of an entirely separate piece of equipment.

Is this unit suitable for outdoor installation?
The RIBX24BA is housed in a NEMA 1 rated enclosure, which is intended for indoor use. For outdoor applications, it must be installed within a secondary weather-proof junction box.
