MSD 7-20V 140A High Current Solid State Relay Block, 4x 35 Amps, Black

Clean up your wiring with an MSD Solid-State High Current Relay Block. This high current module takes the place of 4 standard relays and eliminates unsightly wiring. Four independent channels can be activated using either power or ground. Each channel is capable of handling up to 35 Amps of continuous current, providing up to 140 Amps of power. It also has the capability of Pulse Width Modulation (PWM). With a PWM input, you can control the output at a rate of 15 hertz and a duty cycle of 50-90%. Controls electric fans, water pumps, nitrous solenoids, auxiliary lighting and any other electrical accessories that would normally require a relay.

LED status indicators ensure proper wiring and operation of each channel. Should a problem arise, the relay block has built-in automatic over-temp, short circuit, and overload protection, as well as a channel reset. The solid-state high current relay can easily be mounted using the supplied hardware and mounting tabs that can be rotated 90° to accommodate various mounting locations. It’s compact and clean design will make your wiring project a breeze.
