Functional Devices RIB2401SB-NC Relay
The Functional Devices RIB2401SB-NC is an enclosed 20 Amp SPST-NC power relay engineered for heavy-duty commercial HVAC and automation control. This single pole single throw normally closed relay features a dual-coil input compatible with both 24VAC/DC and 120VAC, providing versatile integration for building management systems (BMS). The "SB" configuration indicates a split-brain relay design, separating the sense and power circuits to ensure reliable switching of inductive loads. Encased in a NEMA 1 rated housing, this pre-wired relay simplifies installation with 14-inch leads and a 1/2-inch NPT nipple for direct mounting to electrical boxes. The integrated Override Switch allows technicians to manually control the load during system commissioning or troubleshooting without requiring a controller signal. High-current silver cadmium oxide contacts ensure long-term durability when managing 20A resistive loads, motor branch circuits, and lighting ballast applications.
Key Benefits for Contractors- Dual-coil input flexibility supports 24V or 120V control signals within a single device.
- SPST-NC configuration ensures the load remains energized in the absence of a control signal, critical for fail-safe operations.
- Manual Override Switch provides immediate field control for testing motor loads or lighting circuits.
- NEMA 1 Enclosure protects internal components while the external LED indicator provides visual status of coil activation.
- Pre-wired leads reduce labor time and eliminate the need for complicated internal terminal wiring.
Can this relay be used with DC control voltages?
Yes, the 24V input coil is designed to operate on either 24VAC or 24VDC, making it ideal for various low voltage control applications.
What is the maximum amperage rating for motor loads?
The RIB2401SB-NC is rated for 1 HP at 120VAC and 2 HP at 277VAC, suitable for most high-torque HVAC blower motors.
What is the purpose of the split-brain design?
The split-brain architecture isolates the coil voltage from the contact voltage, preventing electrical interference and enhancing safety during field service.
