The Uni Trac is an industrial data acquisition (DAQ) device with two reading channels. It enables the reading of industrial sensors through multiple protocols and sends the collected data to the Tractian platform.
Main Features
Two configurable reading channels
Supported protocols: 4–20 mA, 0–10 V, NPN, PNP, I2C, RS485
Battery-powered (up to 3 years of battery life) or external power supply
IP67 protection rating (water- and dust-resistant)
Field installation with magnetic mount or plastic cable ties (width ≤ 10 mm)
Male M12 connector, 5 pins (A-coded)
Supported Communication Interfaces
The Uni Trac can be factory-configured to support different types of sensors:
Interface Type | Channel 1 | Channel 2 |
Analog (0–10 V, 4–20 mA) | Yes | Yes |
Digital (NPN, PNP, dry contact) | Yes | Yes |
RS485 | Line A | Line B |
I2C | SCL | SDA |
Important notes:
The selection between NPN and dry contact is made via firmware command.
Make sure the sensor is compatible with the available channels.

Installation Diagrams
Refer to the specific diagrams for each sensor type and power supply mode (manual pages 4 to 6). Examples:
0–10 V sensor with 3 or 4 wires (battery or external power supply)
4–20 mA sensor with 2, 3, or 4 wires
NPN or PNP digital sensor
Dry contact
RS485 and I2C communication interfaces
Each diagram shows the correct connection to the M12 connector pins, in compliance with IEC 61076-2-101.
Physical Installation and Connector
Secure the Uni Trac using cable ties or a magnetic mount.
Use the 5-pin M12 connector:
Pin 1: V+
Pin 2: Channel 1
Pin 3: V−
Pin 4: Channel 2
Pin 5: Reserved / NC
Make sure to follow the diagram corresponding to the sensor type and power supply condition used.
