Functional Devices RIB24Z Relay

For contractors managing high-current HVAC and building automation loads, the Functional Devices RIB24Z offers a professional-grade solution in a pre-wired, NEMA 1 enclosure. This enclosed power relay features a 30 Amp resistive rating at 300 Vac, making it ideal for large fans, pumps, and lighting circuits. The 24VAC/DC coil is highly versatile for various control systems, and the integrated LED indicator provides immediate visual confirmation of the relay status at the device. With both SPST-NO and SPST-NC contacts, you can simultaneously manage normally open and normally closed circuits from a single command signal. This RIB relay eliminates the need for field-assembled components, saving significant labor time in the mechanical room. The RIB24Z relay is UL Listed for use in plenum spaces, ensuring compliance with strict building codes while providing a compact hub-mounted footprint that integrates easily into standard 1/2" NPT knockouts.

• High-Capacity Switching: Rated for 30 Amps, capable of handling 3 HP loads at 480-600 Vac without requiring external contactors.
• Plenum Rated Safety: The NEMA 1 housing is accepted for use in plenum environments, simplifying installation in dropped ceilings.
• Pre-Wired Efficiency: Includes 16-inch, 600V color-coded leads to prevent wiring errors and reduce on-site labor costs.
• Mechanical Durability: Engineered for extreme reliability with a minimum of 10 million cycles for long-term HVACR operation.

What is the difference between SPST-NO and SPST-NC on the RIB24Z?
The RIB24Z features one Normally Open (NO) pole and one Normally Closed (NC) pole. When the 24V coil is energized, the NO pole closes to power the load while the NC pole opens, allowing for simultaneous control of two different circuit states.

Can the RIB24Z be used for 24VDC control signals?
Yes, the 24VAC/DC coil is designed to accept either alternating current or direct current trigger signals, providing flexibility for different DDC and BAS controllers.

Does this relay require a separate mounting base?
No, this is a Relay in a Box unit. It features a built-in 1/2" NPT nipple that allows it to mount directly to a junction box or panel knockout, providing a completely self-contained solution.
