CONELCOM GmbH

CONELCOM GmbH is an Austrian industrial automation company that develops and sells the CONTROLLINO line of programmable logic controllers (PLCs). The brand is built around the idea of "democratizing industrial automation with open source PLCs" — industry-grade controllers that are fully compatible with the Arduino open-source ecosystem, allowing engineers to avoid vendor lock-in and fixed cycle times typical of traditional proprietary PLCs. The company is headquartered in Innsbruck, Austria, and was founded in 2016 by Marco Riedesser, who started the project in a garage after being asked to repair an expensive coffee machine and deciding to build a robust, Arduino-based industrial controller instead of using hobbyist modules. The product range includes the MINI, MAXI, MEGA and MICRO series, along with accessories such as pin headers, screwless terminals, sockets, replacement parts, relays and training kits. CONTROLLINO controllers offer Ethernet, USB and serial connectivity, support for Modbus TCP, 12V and 24V power with automatic switching, digital and analog I/O, and relays rated up to 16A/250V. The brand has grown from a garage startup into an international business serving industries worldwide. In 2024, the company ended its collaboration with Industrial Shields (Boot&Work Corp. S.L.) and confirmed that the CONTROLLINO brand, products, development and support remain with Beans & Bits GmbH, ensuring uninterrupted supply. The official website is controllino.com, and sales and support are handled directly by the CONTROLLINO team.

CONELCOM GmbH was founded in 2016 in Innsbruck, Austria, by Marco Riedesser. The idea for CONTROLLINO originated when Riedesser was asked by a friend to repair an expensive coffee machine. He wanted to use an Arduino to fix it and add new features, but realized that standard Arduino boards with relay modules were not robust enough for industrial use. Surprised that no one offered industrial controllers based on an open platform like Arduino, he decided to build one himself. The project started in a garage in the Alps region of Innsbruck. Over time, CONTROLLINO grew from a garage startup into an international business, with a small team of engineers, developers and visionaries. The product line expanded to include the MINI, MAXI, MEGA and MICRO controllers, along with a range of accessories and kits. The brand emphasizes open-source, Arduino compatibility, and freedom from vendor lock-in. In 2024, the company ended its collaboration with Industrial Shields (Boot&Work Corp. S.L.) and reaffirmed that the CONTROLLINO brand, products, development and support remain with Beans & Bits GmbH. The company continues to sell and support its products directly through its website, controllino.com.
