Clean up your wiring with an MSD Solid State Relay Block. This module takes the place of 4 standard relays and eliminates unsightly wiring. 4 independent channels can be activated using either power or ground. Each channel is capable of handling 50 Amps for up to 8 seconds or 20 Amps of continuous current. With 4 channels providing up to 200 Amps of momentary or 80 Amps constant combined power, you can easily control electric fans, water pumps, nitrous solenoids, auxiliary lighting and any other electrical accessories that would normally require a relay.
