The Advanced Central Logger (ACL) is a highly configurable data acquisition and communications tool that is well suited to professional teams who place serious demands on their data equipment. With 1 GB of logging memory it forms the heart of MoTeC's Central Logging System, which also includes multiple SVIMs Synchronous Versatile Input Modules for high resolution sensor inputs.

The ACL performs data logging, data communication and sophisticated calculations, acquiring data from other MoTeC devices such as an ECU, Dash Logger and up to eight SVIMs, which enable it to log more than 200 inputs. It provides all the advanced features of MoTeC Display Loggers, including warning alarms, fuel prediction, engine logs, timers, tables, user conditions and telemetry. For maximum flexibility the ACL connects to any MoTeC display.

MoTeC’s Central Logging System follows a modular concept, employing separate dedicated devices for inputs, and logging, thereby allowing customers to tailor a solution to their application. The system is simple to set up as most connected devices are configured and upgraded from one software application.

The ACL comes as standard with Pro Analysis enabled, allowing unrestricted use of MoTeC’s professional level i2 Pro data analysis software.
