MSD Solid State Relay Blocks Make Wiring Simple

By: Todd Veney | 08/09/2017 < Back to Motor Life Home

MSD's award-winning Solid State Relay Block eliminates wiring headaches and cleans up any engine compartment, taking the place of four standard relays. Four independent channels can be activated using either power or ground, and each is capable of handling up to 20 amps of continuous current, providing up to 80 amps of power. This compact, efficient module is perfect for controlling electric fans, water pumps, nitrous solenoids, auxiliary lighting, or any electrical accessory that would normally require a relay. LED status indicators ensure proper wiring and operation of each channel, and if a problem should arise the relay block has built-in automatic over-temp, short-circuit, and overload protection. Available in both red and black, it even comes complete with all the necessary hardware for a fast, easy installation and can be rotated 90 degrees to accommodate numerous mounting locations.
