Description
The Functional Devices RIBT2401B is a robust enclosed relay designed for dependable switching in HVAC, building automation, and light commercial control applications. Featuring a 24VAC/DC coil, this relay accepts the standard 24-volt control signal found throughout HVAC systems and uses it to switch 120V loads at up to 20 amps — making it well-suited for controlling fans, pumps, compressors, lighting circuits, and other line-voltage equipment.
The RIBT2401B is part of Functional Devices’ industry-trusted RIB® (Relay in a Box) product line, recognized for its compact, self-contained enclosure that simplifies installation and protects internal components. The SPDT (Single Pole Double Throw) contact configuration provides both normally open (NO) and normally closed (NC) switching flexibility, allowing the relay to be wired for a wide range of control sequences.
