Functional Devices RIBT2401SB Relay

The Functional Devices RIBT2401SB is an enclosed 20 Amp pilot control relay designed for reliable switching in HVAC, lighting, and industrial control applications. This SPST-NO (Single Pole Single Throw, Normally Open) relay features a pre-wired enclosed design that eliminates the need for an external electrical box, streamlining installation on standard 1/2-inch knockouts. It operates with a dual-coil voltage input supporting 24Vac/dc or 120Vac, making it compatible with most BAS (Building Automation Systems) and thermostat controllers. The integrated override switch allows technicians to manually bypass the coil for diagnostic testing and maintenance. Engineered for high-load performance, the relay is rated for 20A resistive loads and is capable of handling motor loads up to 1 HP at 120V. Its UL Listed housing ensures safety and durability in demanding mechanical rooms, providing a professional-grade interface for controlling fans, pumps, and heating elements.

• Integrated Override Switch: Simplifies troubleshooting by allowing manual control of the load regardless of the controller state.
• Versatile Input Voltage: The 24Vac/dc and 120Vac coil options reduce the need to stock multiple SKUs for different job sites.
• NEMA 1 Enclosure: Includes a 1/2-inch NPT nipple for direct mounting to junction boxes, keeping high-voltage and low-voltage wires separated.
• Heavy-Duty Contacts: Rated for 20 Amp inductive and resistive loads, ensuring long-term reliability for motor and lighting circuits.
• LED Status Indicator: Provides immediate visual confirmation of the relay coil energization.

Can the RIBT2401SB be used for both AC and DC switching?
The relay contacts are rated for AC loads up to 277V. While the 24V coil can accept DC, always verify the specific inductive flyback requirements of your DC load before installation.

What is the purpose of the 'H/L' designation in the specifications?
This refers to the High/Low voltage separation. The encapsulated design keeps the high-voltage load wires separate from the low-voltage control wires to meet local electrical codes.

How does the override switch impact automation?
When set to 'On' or 'Off', the manual switch overrides the logic from the 24V controller. Ensure the switch is set back to 'Auto' after service to return control to the BAS.
