Integrated Sensors (GPS/GNSS and IMU)
The device is equipped with 3 integrated modules essential for the dynamic analysis of the vehicle or machinery:
GPS/GNSS Receiver: Integrated module with a 10 Hz update rate. The antenna is external.
Inertial Measurement Unit (IMU): 6-axis sensor (3-axis accelerometers + 3-axis gyroscopes) rigidly mounted on the internal PCB. It allows the measurement of longitudinal/lateral accelerations and roll, pitch and yaw angles.
Accelerometers +/- 30g, internal sampling 1125Hz, low-pass filter 68.8Hz
Gyroscopes +/- 2000°/sec, internal sampling 1125Hz, low-pass filter 73.3Hz
Analogue Inputs (AN1 – AN8)
The data logger features 8 analogue inputs with a 12-bit ADC converter. The inputs are divided into two categories to ensure maximum compatibility with industrial and motorsport applications:
Standard 0-5V channels (AN1 – AN4): High-impedance voltage inputs, ideal for reading potentiometers, pressure sensors and pre-amplified thermocouples. Maximum voltage tolerance: -0.3V to 5.3V.
0-20mA / 4-20mA Current Channels (AN5 – AN8): These 4 inputs are internally equipped with a 250 Ohm precision pull-down resistor to ground. They allow ‘Plug&Play’ connection of industrial current sensors without additional hardware.
Digital / Frequency Inputs (DI1 – DI4)
The 4 digital inputs are designed for reading pulse signals (wheel speed sensors, motor RPM, flow meters, tacho sensors).
Frequency and Accuracy: The calculation of Hertz is handled by a very high-frequency hardware counter, which guarantees virtually zero latency for signals from 1 Hz to 20 kHz.
Logic Thresholds (Triggers): The signal is considered “HIGH” above 2.5V and “LOW” below 1.0V. The maximum voltage tolerated on the pin is the battery voltage (VBatt).
CAN Bus Interface
The system incorporates a CAN bus capable of handling up to 16 channels simultaneously.
Transceiver: High-Speed CAN 2.0B.
Protocols: Using the GUBELLINI DataStudio software, the CAN bus can be configured according to the OBD II, SAE J1939, ISOBUS (ISO 11783) and OpenCAN (EN-50325-4) protocols.
Termination: The 120-ohm termination resistor is built into the data logger.
Digital Outputs
The system incorporates two digital outputs linked to two programmable software alarms (based on input values) that allow a 0-5V signal to be generated. These same two outputs can drive two relays to activate external actuators (such as motors, solenoid valves, pumps or other devices).
Voltage signal: 0-5V.
Relays: relay control via external power supply.
Maximum load: Max. drain voltage 60V, Max. current 1.5A
CAN Bridge
This mode allows you to create a bridge between ‘physical’ inputs (GPS, IMU, digital inputs and analogue inputs) and the CAN bus. You can transmit the values detected on the physical inputs directly to the CAN bus. In this mode, the CAN input channels will not be taken into account. In this mode, the input data will not be recorded on the SD card.
Protection and Operating Environment
The Datalogger guarantees an IPX7 rating, allowing for use in harsh environments. The guaranteed operating temperature range is from -20°C to +85°C
Internal memory
The logged data is saved to an unformatted micro SD card (RAW format). The supported micro SD card capacities are 16, 32, 64 and 128 GB (larger capacities are supported but not utilised to their full capacity). The micro SD card can be removed and connected directly to a PC to retrieve the data (organised into datasets) using the dedicated function in GUBELLINI DataStudio.
Auto-Start Conditions
The data logger can manage the start of recording in two modes: “Always On” and “Auto-start Condition”. In “Always On” mode, the data logger generates a new dataset number and begins recording data from the active inputs immediately. The dataset closes when the device is switched off. In “Auto-Start Condition” mode, the data logger generates a new dataset number and begins recording data only after a condition has been met (linked to the value of one of the active inputs). The “Auto-Start” condition is programmable via software. The dataset is closed and recording stops when the device is switched off.
Artificial Intelligence
The GUBELLINI DataStudio data logger management software is equipped with an AI module called AI Analyst. AI Analyst is an innovative way of analysing the data recorded by the data logger. AI Analyst is not a simple AI “chatbot” to which you ask generic questions, but a fully-fledged multi-agent artificial intelligence system integrated into the software. It has been designed to assist you in analysing the acquired data, automating the search for anomalies, the creation of complex graphs and the drafting of professional reports.
Power supply
The device can be powered by a DC voltage of 7 to 24V. The main connector provides a 5V supply voltage for connected sensors.
USB-C connection
You can connect to the data logger via a USB-C connector located on the side of the housing and protected by a rubber seal. Via the USB connection, you can: send and receive configuration data, monitor the values of active inputs in real time, and download recorded data organised into datasets. Transmission limit: 1 Mbps.
Main Connector: JAE MX23A26NF1 (Automotive Grade)
To ensure maximum reliability in signal transmission and maintain IPX7 waterproof certification, the physical interfacing of all channels (analogue, digital, CAN Bus and power supply) is handled by a single automotive-grade connector: the 26-pin JAE Electronics MX23A26NF1.
The MX23A series has been specifically designed for the automotive and motorcycle industries for use in exposed areas (engine compartments, external frames, agricultural machinery). It features technical specifications of the highest standard:
Waterproof: The connector is fitted with silicone seals (sealing rings) at the mating interface and individual rubber seals for each inserted cable, preventing the ingress of water, oil and dust.
Vibration Resistance: The mechanical snap-lock system (Click-Lock) ensures that the connector does not accidentally come loose, even when subjected to the extreme stresses of a single-cylinder engine or the kerbs of a racetrack.
Electrical Protection: The low-profile housing physically separates the pins to prevent short circuits caused by moisture.
