Functional Devices RIB24P Relay

The Functional Devices RIB24P is a high-performance DPDT enclosed relay engineered for demanding HVACR and building automation systems. Built as part of the industry-standard "Relay in a Box" series, this 20A power control relay eliminates the need for external sockets or mounting rails by featuring a pre-wired, NEMA 1 plenum-rated housing. The dual-pole double-throw configuration provides superior switching flexibility, allowing for the simultaneous control of two separate circuits or the isolation of different voltage levels. Its universal 24VAC/DC coil is designed for low current draw, ensuring compatibility with standard 24V control transformers and digital controllers.

For technicians in the field, the RIB24P relay simplifies installation with its 1/2-inch NPT nipple and 16-inch 600V rated wire leads. The gold flash contacts ensure reliable low-level switching, while the externally visible LED provides immediate status verification. This unit is specifically rated for inductive and resistive loads, including 3 HP motors at 480V and 20A ballast applications, making it a rugged solution for commercial fan control, lighting circuits, and interlock logic.

• All-in-One Design: Integrated enclosed relay includes the housing and pre-wired leads to reduce job site labor and component costs.
• Versatile Load Handling: Rated for 20A resistive loads and high-voltage motor switching up to 3 HP, suitable for industrial HVACR machinery.
• Reliable Switching: Features gold flash contacts to prevent oxidation and ensure continuity in low-voltage signaling or power circuits.
• Instant Diagnostics: Integrated LED status indicator allows for rapid troubleshooting of the 24V signal without opening the enclosure.
• Code Compliance: UL Listed for UL916 Energy Management and UL864 Fire Alarm standards, meeting strict safety protocols for commercial installations.

What is the difference between the RIB24P and standard ice cube relays?
The RIB24P is a completely self-contained 20A DPDT relay. Unlike ice cube relays that require separate bases, DIN rails, and enclosures, the RIB24P is pre-packaged in a plenum-rated housing that mounts directly to a conduit knockout.

Can I use this relay for both AC and DC control signals?
Yes, the RIB24P coil is designed to operate on either 24VAC or 24VDC. It features a wide pull-in range and low current consumption, making it compatible with most BAS and HVAC controllers.

Is this relay suitable for switching high-voltage lighting ballasts?
Absolutely. This unit is rated for 20A ballast loads up to 480VAC. The DPDT configuration also allows you to switch multiple phases or separate circuits from a single 24V trigger.
