MSD High-Current Solid-State Relay 4-Channel 35A Red 7564-HC

Managing multiple high-power electrical accessories—from electric fans to nitrous solenoids—typically requires separate relays, complex wiring, and potential reliability issues. The MSD 7564-HC consolidates four independent relay channels into a single, compact solid-state module, eliminating clutter while delivering rock-solid switching for up to 140 amps of combined current. Whether you're building a street machine or a dedicated race car, this relay simplifies your electrical architecture and gives you precise PWM control over critical systems.
