Functional Devices RIBU1C-RD Relay

The Functional Devices RIBU1C-RD is a professional-grade enclosed pilot relay engineered for versatile control in building automation and HVAC systems. This 10 Amp SPDT relay features a multi-voltage coil, accepting 10-30 VAC/DC or 120 VAC, which eliminates the need for multiple stocking units on the truck. Encased in a durable NEMA 1 rated red housing, this unit is specifically designed for quick identification in fire alarm and emergency safety circuits. The RIBU1C-RD is UL listed for energy management (UL916) and fire signaling (UL864), ensuring compliance with strict commercial codes. With a mechanical life rating of 10 million cycles and an integrated LED status indicator, this RIB relay in a box provides field technicians with a reliable, pre-wired solution. The 16-inch color-coded leads and 1/2-inch NPT nipple allow for seamless nipple-mounting and immediate integration into existing junction boxes or control panels.

• Universal Input: Supports both low-voltage (10-30V) and line-voltage (120V) inputs for maximum field flexibility.
• Pre-Wired Reliability: Includes 16-inch, 600V rated leads to reduce installation time and prevent wiring errors.
• Code Compliant: Certified under UL864 and UL916, making it suitable for fire alarm and energy management applications.
• LED Status Monitoring: High-visibility LED provides instant visual confirmation of relay activation.
• Plenum Rated: Safe for use in environmental air spaces, meeting standard NEMA 1 enclosure requirements.

Can I use the RIBU1C-RD for motor loads?
Yes, the contacts are rated for 1/3 HP at 120-240 VAC (N/O) and 1/6 HP (N/C), making it suitable for small exhaust fans or pump starters.

What is the purpose of the red housing?
The red color is the industry standard for fire alarm, safety, and emergency circuit identification, helping technicians quickly locate critical control points.

Does this unit require a separate transformer?
No, its wide coil voltage range allows it to be powered directly from most standard control power sources, including 24V class 2 circuits or 120V mains.
