The Kussmaul Relay Board 4 provides a compact, organized solution for controlling multiple electrical loads in fire apparatus, ambulances, rescue vehicles, command vehicles, and other specialty vehicle electrical systems. Designed to simplify installation and reduce wiring complexity, the Relay Board 4 combines four individually controlled relays into a single assembly, eliminating the need to separately mount and wire multiple individual relays.

Each relay is energized independently through the integrated terminal strip and features an adjacent LED indicator that illuminates whenever the relay is active, providing convenient visual confirmation of circuit operation. Electrical loads connect directly to the top of the relays using 1/4-inch quick-disconnect terminals, while both normally open and normally closed contacts provide flexibility for a variety of switching applications. Available in configurations for 12V and 24V electrical systems, the Relay Board 4 can be controlled by applying voltage to the relay coil or by grounding the relay coil, depending on the model selected. The assembly is compatible with Kussmaul Load Manager systems and is backed by a 3-year manufacturer's warranty.
