Functional Devices RIBTD2401B Enclosed Time Delay Relay 20A SPDT with 24V AC/DC/120V AC Coil

Deliver consistent, code-compliant timed control across security, fire and building automation systems with the Functional Devices RIBTD2401B enclosed time delay relay. This 20A SPDT relay gives integrators and facility managers dependable switching for access control, surveillance cameras, door strikes, alarm signaling and HVAC interlocks. Its low-current coil accepts 24V AC/DC or 120V AC, offering flexible wiring options that reduce the need for multiple relay types on the truck. Color-coded leads simplify installation and troubleshooting, cutting labor time and minimizing wiring errors on site. The RIBTD2401B is UL listed to both UL916 (Energy Management) and UL864 (Fire), making it suitable for monitored fire panels and energy-control applications that require certified components. With a compact enclosed package and a durable 20A contact rating, it supports higher current loads while maintaining clean, repeatable timing performance for monitoring and security systems. Upgrade your control panels with a relay designed for real-world installations — ideal for contractors, integrators and building engineers. Add the RIBTD2401B to your next security or fire control project to streamline installation and ensure reliable timed operation.
