MSD's new line of relay modules is an affordable and efficient solution for controlling high voltage and current electronics in vehicles. With single, dual, and 4 channel options available, these modules are designed to simplify wiring and installation in most automotive electrical systems. They offer independent 40A outputs and configurable single-wire activation, along with LED status indicators and low profile JCASE fuses for protection. The plastic cover of the relay housing ensures a tidy installation and safeguards the main power stud and triggers against contamination and accidental contact.
