Ecumaster Battery Isolator is a motorsport master relay device
designed for FIAcompliant battery isolation and engine shutdown.
The device is designed for harsh motorsport environments and weighs
only 83g. Featuring a full solid-state design, an absence of mechanical
components ensures long life and high reliability.
The device has built-in alternator load dump protection without the
addition of any external components.
There is no risk of damage to expensive electronic equipment during
emergency shutdown. The isolator is controlled with two external
switches and can be shut down with a CAN-bus message.
The message may be sent from an Ecumaster PMU16 unit in the case
of impact or another event. The device is configurable through CANbus.
It also sends diagnostic information which can be used by other
equipment and is valuable during device setup and diagnosis. It is fully
protected against overheating and over-current.
Device status is indicated with a multi-color led light.
