MDL-700 Description

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

MDL-700 is purpose-built by Dyacon engineers for environmental and site monitoring applications. System architecture is tuned to the unique needs of remote data collection and control, low power, PC-like I/O, and expandable sensor input and control options.

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.

Key Features


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


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 input requirements for 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. Expansion boards may be attached to the left or right sides.

Left side board include power input and control output options.

Right side expansion modules add sensor inputs and low-current control output.
