Functional Devices RIBM24C Relay

The Functional Devices RIBM24C is a professional-grade track mount pilot relay designed for seamless integration into building automation systems (BAS) and HVAC control circuits. Engineered for high-reliability switching, this 15 Amp SPDT relay features a versatile 24Vac/dc coil, making it a go-to component for contractors managing 24V control circuits. The unit is specifically designed for 4-inch mounting tracks, allowing for high-density relay packaging in mechanical rooms or control panels. This SPDT pilot relay includes a built-in LED indicator for immediate visual confirmation of relay status, reducing diagnostic time during field service. With a mechanical life rating of 10 million cycles and a continuous duty coil, the RIBM24C handles inductive and resistive loads up to 15 Amps at 125 Vac, ensuring durable performance in demanding commercial environments. Its track-mounted form factor and screw terminal connections streamline the wiring of fans, pumps, and staged heating applications.

• Universal 24V Compatibility: Functions efficiently with both 24Vac and 24Vdc power sources for flexible site application.
• High-Density Mounting: Snaps directly into a 4-inch MT4 mounting track to save valuable panel space.
• Visual Diagnostics: Integrated LED provides a clear "on/activated" status without requiring a multimeter for initial checks.
• Substantial Load Capacity: Rated for 15 Amp general use, capable of controlling pilot duty loads and small motor circuits.
• Rugged Temperature Range: Operates reliably from -30°F up to 140°F, suitable for unconditioned mechanical spaces.

How do I wire this relay for a normally closed application?
To utilize the normally closed (N/C) function, land your lead on the N/C terminal and the common terminal. This Functional Devices relay provides a Form C SPDT contact, allowing for both N/O and N/C configurations depending on your circuit requirements.

Can I use the RIBM24C to start a 1/2 HP motor?
Yes, the internal contacts are rated for 1/2 HP at 125 Vac and up to 1 HP at 250 Vac, making it an excellent choice for small exhaust fans or pump starters in HVAC control systems.

Does this unit require a specific orientation for installation?
No, the RIBM24C can be mounted in any orientation within the 4-inch plastic track, provided the ambient temperature and humidity remain within the 5% to 95% non-condensing range.
