ACC3 Open: Versatile Analogue CAN Converter
The Aim Analogue CAN Converter (ACC3 Open) combines a compact design with powerful
performance, managing up to 4 channels at 200Hz each while adding the flexibility of CAN output.
Perfect for teams integrating Aim sensors with third-party data systems or sharing data across multiple devices, the ACC3 Open offers unmatched versatility.
Fully compatible with the Aim Solo 2 DL, it gives you freedom beyond the Aim Technologies ecosystem.
Why Choose the Aim ACC3 Open
Building on the strengths of the standard ACC3, the ACC3 Open adds open CAN communication, making it ideal for mixed-system environments.
In addition to supporting 4 analogue inputs and 2 speed inputs, the ACC3 Open can output data via CAN, enabling seamless communication with third-party systems such as MoTeC, Pi, VBOX, Cosworth, Bosch, and other motorsport brands.
With the ability to define bit rate protocols, field messages, and payload structures, it gives you complete control over how your data is transmitted and integrated.
The ACC3 Open can function as a standard Aim expansion or as a cross-brand interface, offering a future-proof solution that ensures your sensors and data remain compatible — even as your setup evolves.
Sensor Compatibility
The ACC3 Open supports up to 4 analogue inputs (up to 200Hz) and is compatible with a wide range of motorsport sensors, including:
Thermocouples (K type) – using dedicated compensated cables
Thermo Resistors
0–5V Sensors
0–12V Sensors
It also includes 2 speed inputs (internal pull-up for open drain/collector input), providing flexibility for monitoring wheel speed, driveshafts, or auxiliary channels.
Advanced CAN Output
What sets the Aim ACC3 Open apart is its ability to build a dedicated CAN output for communication with external systems.
You can customise:
Bit rate protocols
Field messages
Payload details
This ensures compatibility with virtually any motorsport data network.
Whether used as a standalone CAN output module or a native Aim expansion, the ACC3 Open offers complete control over data flow — allowing you to share and analyse information exactly the way you need.
Channel Configuration
After selecting the appropriate harness, each channel can be configured for the sensors in your setup.
The ACC3 Open supports up to four K-type thermocouples, providing accurate temperature monitoring across multiple areas of your vehicle for enhanced tuning and diagnostics.
Suspension Analysis
Pair the ACC3 Open with Aim Eclipse sensors and linear potentiometers for detailed suspension analysis.
Using Race Studio 3, you can process and visualise chassis movement data to gain a comprehensive understanding of vehicle dynamics, helping you refine suspension setup and optimise on-track performance.
