PRODUCT DESCRIPTION
The Ecumaster Battery Isolator is a motorsport master relay designed for battery isolation and engine shutdown compliant with FIA regulations. Designed for demanding motorsport environments, it weighs only 83g. Its all solid-state design, with no mechanical components, ensures a long service life and high reliability. It incorporates alternator overvoltage protection without the need for external components. There is no risk of damaging expensive electronic equipment during an emergency shutdown. The isolator is controlled by two external switches and can be turned off via a CAN-bus message. This message can be sent from an Ecumaster PMU16 unit in the event of an impact or other event. The device is configurable via CAN-bus. In addition, it sends diagnostic information that other equipment can use, which is valuable during setup and diagnosis. It is fully protected against overheating and overcurrent. The device status is indicated by a multi-color LED. Key Features
