Functional Devices RIB01BDC Relay

The Functional Devices RIB01BDC Relay is a heavy-duty 120V 20A SPDT dry contact relay engineered for reliable switching in HVAC, lighting, and building automation circuits. This "Relay in a Box" features a single-pole double-throw continuous duty coil that provides a mechanical life of 10 million cycles, ensuring long-term performance in demanding commercial environments. Designed for fast integration, it includes a 0.50 inch NPT nipple for easy mounting to electrical boxes and 16-inch 600V rated wire leads. The NEMA 1 housing is UL accepted for use in plenum spaces, making it a go-to solution for contractors managing air-handling unit interlocks or fan status monitoring. An integrated LED status indicator provides immediate visual confirmation of relay activation, simplifying troubleshooting during system commissioning.

Key Benefits for Contractors

• High Current Capacity: Rated for 20 Amp resistive loads, making it suitable for motor and ballast switching.
• Versatile Mounting: The pre-installed 0.50" NPT nipple allows for exterior mounting to any standard junction box.
• Plenum Rated: The rugged NEMA 1 enclosure meets safety standards for installation within environmental air spaces.
• Ready for Field Use: Includes pre-stripped 16-inch wires to reduce installation time on the job site.
• Wide Operating Range: Functions reliably in extreme conditions from -30°F to 140°F.

Common Questions

Is the RIB01BDC suitable for inductive loads?
Yes, while it handles 20A resistive, it is also rated for 1 HP at 120V AC and 2 HP at 277V AC, making it ideal for fan and pump motors.

Can I use this relay for 24V control circuits?
The RIB01BDC specifically requires a 120V AC coil input. If your control signal is 24V AC/DC, you should look at the RIBU1C or RIB24B models.

What is the purpose of the dry contact configuration?
The dry contact relay design provides an isolated switch, allowing you to control a high-voltage circuit using a separate power source without electrical interference between the two.
