Functional Devices RIB12P Relay

The Functional Devices RIB12P is a heavy-duty, DPDT enclosed power relay engineered for reliable control of high-current HVAC and building automation loads. Designed for professional installation, this 20 Amp pilot relay features a 12 VAC/DC coil, making it compatible with specialized low-voltage control circuits often found in legacy security systems and specific industrial controllers. The double-pole double-throw (DPDT) configuration allows for the simultaneous switching of two separate circuits, providing a compact solution for interlocking equipment or managing multi-stage hardware from a single 12V trigger signal. Encased in a NEMA 1 rated housing with 1/2" NPT nipples, this RIB relay mounts directly to a junction box or electrical cabinet. The pre-wired color-coded leads ensure a rapid dry contact relay setup, reducing field labor while maintaining a secure, professional-grade termination. This potted relay design protects internal components against vibration and environmental contaminants, ensuring consistent inductive load switching performance in demanding mechanical room environments.

• Multi-Circuit Control: The DPDT contacts enable simultaneous switching of two independent loads, ideal for motor control and safety feedback loops.
• Versatile Coil Input: Formatted for 12 VAC/DC systems, bridging the gap between low-voltage electronics and high-voltage power loads.
• 20A Rated Contacts: Robust switching capacity suitable for ballast loads, tungsten, and high-duty cycle motors.
• Simplified Installation: External LED indicator provides immediate visual confirmation of coil status, facilitating faster troubleshooting during commissioning.
• NEMA 1 Enclosure: UL Listed housing allows for surface mounting or direct attachment to conduit, requiring no internal wiring of the relay base.

Can the RIB12P be used to control two different voltages?
Yes. Because the DPDT contacts are isolated, you can switch two separate circuits, such as a 120V fan motor and a 24V control signal, simultaneously from the 12V coil.

What is the maximum ambient temperature rating for this relay?
The Functional Devices RIB12P is rated for operation between -30°F to 140°F, making it resilient in non-conditioned mechanical spaces.

Does this unit include an override switch?
The RIB12P is a standard enclosed relay; if manual override is required for testing, specific "RIB12P-HO" or "RIB12P-HI" models should be sourced, or an external toggle should be wired in-line.
