Ecumaster Battery Isolator Club

The Ecumaster Battery Isolator is a motorsport master relay designed for FIA-compliant battery isolation and engine shutdown. Built for harsh motorsport environments, it uses a full solid-state design with no mechanical components for long-term reliability. It includes alternator load dump protection without external components to help prevent damage to sensitive electronics during emergency shutdown.

The isolator is controlled via two external switches and can also be shut down by a CAN-bus message (for example from an Ecumaster PMU16 in the event of an impact). Configuration and diagnostics are available through CAN bus, with built-in protection against overheating and over-current. Status is shown via a multi-color LED indicator.
