Functional Devices RIBT24B-FA Polarized Relay, 20A SPDT, 24VAC/DC Coil, Hi/Lo Voltage Separation, NEMA Housing

Ensure dependable control of high-current loads in security and building systems with the Functional Devices polarized relay RIBT24B-FA. This polarized relay delivers reliable 20A SPDT switching for access control, alarm panels, surveillance cameras and other monitoring equipment. The versatile 24VAC/DC coil accepts both AC and DC control voltages, while built-in Hi/Lo Voltage Separation protects sensitive control electronics and aids diagnostics for faster service calls. Housed in a compact NEMA 1 enclosure (4" x 4" x 1.81"), the RIBT24B-FA installs cleanly in control cabinets or junction boxes and meets the physical demands of commercial installations. The polarized contact design reduces false trips and preserves contact life — minimizing maintenance in mission-critical security and automation deployments. Manufactured in the US, this relay is a practical choice for integrators and facilities managers who need robust, repeatable switching rated for 20 amps on resistive and inductive loads. Ideal for access control, alarm systems, surveillance and HVAC monitoring — order the RIBT24B-FA to improve reliability and simplify installation.
