This MSD Solid State Relay Block cleans up wiring by replacing 4 standard relays in a single compact module. Four independent channels can be activated using either power or ground, with each channel capable of handling 50 amps for up to 8 seconds or 20 amps continuous. Combined, the 4 channels can deliver up to 200 amps momentary or 80 amps constant, enough to control electric fans, water pumps, nitrous solenoids, auxiliary lighting, and other accessories that would normally require a relay.
