Resilient Design: Solid-state PTC technology prevents mechanical wear and contact pitting common in standard relays

Measuring 45 inches in length

Hand-tighten the adapter into the check valve before using a wrench for a final quarter-turn to seat the internal gasket

It maintains the same 8-inch probe dimensions and resistance curve

The industry-standard spade terminal configuration allows for rapid electrical connections

Functional Devices RIB2402B Relay Resilient Design: Solid-state PTC technologyThe Functional Devices RIB2402B Relay is a heavy duty, 20 amp enclosed power relay designed specifically for the rigorous demands of HVAC control systems and industrial automation. Built with a SPDT (Single Pole Double Throw) configuration, this "Relay in a Box" (RIB) provides a reliable interface between low voltage controllers and high voltage loads. It features a multi voltage coil that accepts 24VAC DC or 208 277VAC, eliminating the need for
