Functional Devices RIB2402D Relay

The Functional Devices RIB2402D is a versatile DPDT enclosed relay designed for demanding HVACR control circuits and building automation systems. Built with a 24VAC/DC coil and featuring a 208-277V 10A rating, this pilot device is engineered for switching multiple loads or isolating disparate control voltages. The RIB2402D power relay utilizes a NEMA 1 enclosure, facilitating a secure external mounting directly to electrical boxes via a 1/2-inch NPT nipple. Technicians prefer this double pole double throw relay for its ability to manage high-voltage equipment while maintaining a low-voltage control footprint. Whether you are interfacing with dry contact controllers or managing line voltage switching for motors and heaters, the RIBU2C-type logic ensures reliable contact closure. This industrial relay eliminates the need for field-fabricated enclosures, reducing installation time and providing a clean, professional finish on every service call or retrofit project.

• Dual-Pole Versatility: The DPDT configuration allows for simultaneous control of two independent circuits.
• Multi-Voltage Coil: Accepts both 24VAC and 24DC, making it compatible with legacy 24V systems and modern DC controllers.
• Pre-Wired Design: Features color-coded 18 AWG leads for intuitive field wiring and faster termination.
• Compact NEMA 1 Housing: Protects internal components while allowing for exterior mounting without an additional pull box.
• High Current Capacity: Rated for 10 Amp resistive loads, suitable for various fractional horsepower applications.

Can I use the RIB2402D to switch 277V lighting loads?
Yes, the contacts are rated for 208-277V applications, making this an ideal solution for lighting control or high-voltage fan motors within the 10A limit.

What is the primary difference between this and a standard SPDT RIB?
The RIB2402D provides two sets of contacts (Double Pole), enabling you to switch two separate wires or two different voltages with a single 24V signal.

Is this relay suitable for outdoor use?
No, the NEMA 1 rating is intended for indoor applications. For rooftop or outdoor installs, a NEMA 4 rated RIB would be required.
