Functional Devices RIB2421C-N4 Relay
The Functional Devices RIB2421C-N4 is a professional-grade enclosed pilot relay engineered for demanding HVAC, building automation, and industrial control applications. This 10 Amp SPDT relay features a multi-voltage coil capable of accepting 24 Vac/dc or 120-277 Vac, providing unmatched versatility for field installations. Housed in a rugged NEMA 4X enclosure, this unit is specifically designed for wash-down environments or outdoor exposure where moisture and corrosion resistance are critical. The pre-wired design with 16-inch color-coded leads and a 1/2-inch NPT nipple allows for rapid integration into standard electrical knockouts, significantly reducing labor time on the job site. With a mechanical life rating of 10 million cycles and an integrated LED status indicator for immediate visual diagnostics, the RIB2421C-N4 ensures reliable dry contact switching for lighting loads, motor control, and energy management systems.
Key Benefits for Contractors:
- Universal Coil Voltage: Simplifies inventory by supporting 24V, 120V, 208V, 240V, and 277V inputs in a single device.
- NEMA 4X Protection: Weatherproof and corrosion-resistant housing allows for reliable performance in harsh environments.
- Simplified Installation: The Relay in a Box design eliminates the need for separate sockets or external enclosures.
- Visual Diagnostics: High-visibility LED provides instant confirmation of relay activation for faster troubleshooting.
- Broad Compatibility: Ideal for interfacing between low-voltage controllers and high-voltage line loads.
Common Questions:
- Can this relay be used outdoors? Yes, the NEMA 4X rating ensures the internal components are protected against rain, sleet, snow, and hose-directed water.
- What are the contact ratings? It supports up to 10 Amps for general use at 277 Vac, 1 HP at 250 Vac, and 470 VA pilot duty at 125 Vac.
- Is it Plenum rated? While the -N4 variant is optimized for NEMA 4X environments, it maintains high-quality standards suitable for complex HVAC ducting control logic.
