controllino

Controllino is a family of programmable logic controllers (PLCs) that combines Arduino-based hardware with industrial features suitable for automation and control tasks. The line is designed to bring the ease of Arduino development into DIN-rail mounted industrial environments, enabling hobbyist and professional users to implement machine control, process monitoring, and data acquisition with familiar tools.

Hardware and I/O

Controllino devices are powered from standard industrial 24V DC supplies and emphasize rugged, field-ready design. They provide a mix of digital inputs and outputs, analog inputs, and, in some models, analog outputs or relay outputs. The field I/O are typically isolated from the processor, helping to protect the control electronics from voltage spikes and noise. The hardware is arranged in different form factors to accommodate varying I/O requirements and installation constraints.

Models and configurations

The Controllino family includes several model types, commonly referred to by names such as MINI, MEGA, and MAXI, each offering different counts of I/O channels and combinations of digital, analog, and relay outputs. This modular approach allows users to select a unit that matches the needs of a given automation task, from compact control loops to more extensive process control applications.

Software and programming

Controllino devices are programmable using the Arduino Integrated Development Environment (IDE), allowing users to write and upload sketches using the widespread Arduino ecosystem. This enables rapid development, access to a large library of examples, and straightforward integration with sensors, actuators, and other control components. Communication with other systems can be achieved through standard Arduino interfaces and, in many cases, industrial protocols supported by the platform.

Applications and use

Controllino PLCs are intended for small to mid-size automation projects, prototyping, education, and applications where Arduino-like development meets industrial reliability and DIN-rail mounting. They are used to control pumps, valves, sensors, conveyors, and similar equipment, and to interface with SCADA or data-acquisition systems.
