Functional Devices RIBM2401D 10 Amp DPDT Pilot Relay 4-Inch Track Mount 24 Vac/dc/120 Vac Coil

The Functional Devices RIBM2401D is a modular pilot relay designed for building automation, HVAC, and industrial control applications. Featuring a Double Pole Double Throw (DPDT) contact configuration and a multi-voltage coil rated for 24 Vac/dc or 120 Vac, this relay snaps directly onto a 4.00" MT4 mounting track for clean, organized panel installation.

Part of Functional Devices' RIBM Pilot Series, the RIBM2401D delivers reliable switching for light electrical loads, BAS control circuits, low-horsepower motors, and lighting applications. Its wide coil input range eliminates the need for multiple SKUs across different voltage environments, and the built-in LED status indicator provides instant visual confirmation when the relay is energized.

Modules snap easily into the 4-inch plastic mounting track, allowing installers to mix and match relay ratings in a single enclosure. Input and output connections are made via screw terminals, and wiring can be separated to keep high-voltage and low-voltage circuits isolated. Housings can be stacked vertically or horizontally for flexible panel layouts.
