Ecumaster CAN Bus Battery Isolator Rev 2 – Radlok or M8 Terminal

Ecumaster CAN Bus Battery Isolator Rev 2 – Radlok or M8 Terminal

The Ecumaster CAN Bus Battery Isolator Rev 2 is a motorsport master relay device designed for FIA-compliant battery isolation and engine shutdown.

Built for harsh motorsport environments, the isolator uses a full solid-state design with no mechanical switching components, helping improve reliability, durability, and service life. It also features built-in alternator load dump protection, removing the need for additional external components and helping protect expensive electronic equipment during emergency shutdown.

The device can be controlled using two external switches and can also be shut down using a CAN bus message. This allows integration with systems such as the Ecumaster PMU16, where a shutdown message may be triggered in the event of an impact or other configured safety condition.

Available with either Radlok high-current connectors or M8 nickel-plated terminals, this listing allows you to choose the terminal style best suited to your installation.

Available Terminal Options

Radlok Version
Supplied with Radlok high-current connectors for professional motorsport installations requiring fast, robust high-current connection.

M8 Terminal Version
Supplied with M8 nickel-plated high-current terminals for ring terminal installations.
