Functional Devices RIB2401D Relay

The Functional Devices RIB2401D is a versatile enclosed pilot relay designed for demanding building automation and HVAC control applications. Featuring a 20 Amp SPDT contact rating, this pre-wired relay simplifies installations by eliminating the need for separate electrical boxes. The unit operates on a 24VAC/DC coil voltage or a 120VAC coil input, providing flexibility for various signal sources. Its NEMA 1 housing ensures durability in mechanical rooms, while the 1/2" nipple allows for direct mounting to junction boxes. Also identified as the FUN-RIB24-01D, this dry contact relay is an industry standard for interfacing low-voltage controllers with high-voltage loads. Whether you are managing lighting control systems or motor loads, the gold flash contacts ensure reliable switching performance. This SPDT power relay is essential for technicians needing a rugged, UL-listed solution that reduces labor time and maintains bas system integrity.

• Dual-coil input supports both 24V AC/DC and 120V AC configurations for universal site application.
• 20A SPDT contacts handle heavy inductive and resistive loads without premature failure.
• Pre-wired leads and NEMA 1 enclosure reduce installation labor and protective hardware costs.
• Gold flash contacts provide low-resistance switching for critical signal circuits.
• LED indicator provides immediate visual confirmation of coil activation for rapid troubleshooting.

What is the maximum current rating for the RIB2401D?
The relay is rated for up to 20 Amps resistive at 277VAC, making it suitable for high-power lighting and motor control circuits.

Can the RIB2401D be mounted outdoors?
This model features a NEMA 1 enclosure intended for indoor use. For outdoor applications, a NEMA 4 rated enclosure would be required.

Is the RIB2401D compatible with DC control signals?
Yes, the 24V input terminal accepts both 24VAC and 24VDC, allowing it to interface with a wide range of DDC controllers.
