AiM Channel Expansion CAN Sensor Hub
The AiM Channel Expansion adds compatible sensor inputs to an AiM CAN-based motorsport data system. It accepts up to four analogue channels, or a combination of analogue channels and up to two digital inputs, through standard AiM 4-pin input connectors.
It is designed for installations that need additional pressure, temperature, potentiometer, or compatible digital measurements without using the base channels on the connected AiM data logger. The source record lists compatibility with AiM MXL, EVO3, and EVO4 data-loggers. Confirm the exact logger generation, firmware, cable arrangement, and channel support before ordering.
Channel Expansion inputs
- Up to four analogue channels for compatible 0–5 V pressure, temperature, and potentiometer sensors.
- Up to two digital inputs can be configured on two of the channels where the connected AiM system supports the required input mode.
- Four standard AiM 4-pin input connectors for compatible sensors and wiring.
- CAN connection to the compatible AiM data logger or CAN data system.
The actual sensor range, calibration, channel names, digital modes, power supply, and logging behaviour depend on the connected AiM logger, configuration, firmware, sensors, and wiring. This module is an input expansion device, not a standalone data logger.
Example motorsport applications
A Channel Expansion can be used for additional measurements such as suspension-travel potentiometers, pressure sensors, temperature sensors, or compatible wheel-speed inputs. For example, four travel sensors may be connected through one module where the vehicle system and configuration support that arrangement.
Additional compatible CAN equipment may be used through an AiM CAN data hub or other approved system architecture. Do not assume that every sensor, CAN hub, logger generation, connector, or wiring layout is interchangeable. Confirm the complete system before building the harness.
Installation and configuration checks
- Confirm the connected AiM logger model and current firmware before selecting the module.
- Confirm each sensor type, output range, calibration, connector, power requirement, and cable path.
- Use compatible AiM 4-pin input connectors and protect wiring from heat, abrasion, moisture, and moving parts.
- Configure analogue and digital channels in the supported AiM software, then validate each value against a known reference.
- Check CAN termination, grounding, power supply, and data availability before competition use.
Use the AiM Race Studio 3 Knowledge Hub for configuration and analysis guidance, and AiM Downloads & Documentation for official live software, firmware, and documentation sources.
Official AiM support videos
No dedicated Channel Expansion video has been confirmed in the mapped official library. The module should be configured using the current AiM documentation and the connected logger's supported Race Studio workflow. Visit the AiM Academy Training Videos page for the broader official library.
Channel Expansion FAQ
What does the AiM Channel Expansion do?
It adds compatible sensor inputs to an AiM CAN-based data system, allowing additional analogue or supported digital channels to be recorded by a compatible connected logger.
How many sensors can it connect?
It accepts up to four analogue channels, or a combination of analogue channels and up to two digital inputs, using four standard AiM 4-pin input connectors.
Is it a standalone data logger?
No. It is an input expansion device and requires a compatible AiM CAN data logger or CAN system to supply, configure, and record the connected channels.
Which AiM loggers does it work with?
The source record lists AiM MXL, EVO3, and EVO4 data-loggers. Confirm the exact logger generation, firmware, cable arrangement, and channel support before ordering.
What sensors can be connected?
The listing describes compatible 0–5 V pressure, temperature, and potentiometer sensors, with supported digital inputs on two channels. Confirm sensor output, calibration, connector, and system compatibility before ordering.
