Functional Devices RIBT242B 20 Amp 2 SPDT Power Relay 24V AC/DC Hi/Lo Voltage Separation

The Functional Devices RIBT242B is a pre-wired enclosed power relay designed for HVAC, BAS, low-horsepower motor, and lighting control applications. This relay features two SPDT contacts rated at 20 amps with a 24 VAC/DC coil voltage, providing reliable switching and control of heavy electrical circuits including large resistive, motor, and lighting loads.

Key Features:

• Two (2) SPDT power relay contacts rated at 20 amps
• 24 VAC/DC coil voltage with low power consumption
• Hi/Lo voltage separation design with physically separate entrances for input coil and output contact connections
• NEMA 1 plenum-rated housing for safe installation in air handling spaces
• Pre-wired and pre-mounted in housing - eliminates separate component assembly
• LED status indicator shows when relay is activated
• 10 million cycle minimum mechanical life rating for long-term reliability
• Operating temperature range: -30°F to 140°F (-34°C to 60°C)

Technical Specifications:

• Contact ratings: 20A resistive @ 277 VAC, 20A ballast @ 277 VAC, 2 HP @ 277 VAC
• Conduit hub: 1/2" or 3/4" NPT nipple for wire exit
• Wire length: 16 inches, 600V rated
• Operate time: 18ms
• UL Listed (UL 916 Energy Management, UL 864 Fire), cUL Listed, CSFM approved

The RIBT series design allows relay contact wires to exit through the NPT nipple while coil drive wires enter through the removable cover via separate openings, providing clean voltage separation. Coil wires are secured to screw terminals within a dedicated wiring compartment. This pre-assembled "Relay In a Box" design saves installers significant time and expense compared to purchasing and assembling separate relay components.
