MDL-700™ is a programmable data logger with a Linux* operating system.

MDL-700 is purpose-built by Dyacon engineers and natively includes specialized I/O required for environmental and site monitoring applications. System architecture is tuned to the unique needs of remote data collection and control.

The open-source operating system allows software developers to utilize familiar programming tools and data interfaces in order to create a custom solution in a short time. Programmers can build applications on their desktop or directly on MDL using Python, C, or C++.

The expandability and programmability of MDL data logger make for an exceptionally versatile system that can be adapted to a broad range of applications. Data connectivity via FTP, MQTT, email, web server, and more are only limited by the needs of the application and creativity of the programmer.

Those migrating from hobby boards will appreciate the integrated system, including display, hardened electronics, and industrial connectors.

MDL-700™ may be programmed to monitor a range of sensors and control outputs using available expansion boards. This makes the system exceptionally adaptable for:

  • Environmental research
  • Remote site monitoring
  • Remote command and control
  • Process automation
  • Equipment testing

Key Features


MDL-700™ uses a solid aluminum base with provisions for both wall and DIN rail mounting.

Expansion boards may be attached in the same base or cable connected to adjacent bases.


Sensor and power connections use 3.81 mm pitch pluggable terminal blocks for easy wiring and maintenance. One connector is used for each sensor port.

Ethernet uses standard 8-pin modular connector. Standard Type-A and B connectors are used for USB host and device connections.


Environmental data logger applications imply unique measurement needs. MDL-700 accommodates a diversity of applications with modular construction. Researchers and sophisticated industrial users can add I/O boards to the base module.
