The Unipi Edge controller combines a PLC, RTU, edge device, IPC, and IoT/IIoT gateway in a single product. It can therefore be used in a wide range of solutions – automation, regulation, and monitoring of building management systems (BMS), HVAC, photovoltaic power plant control, and home or industrial automation systems. Thanks to the Raspberry Pi Compute Module 4, it provides high performance for demanding applications. You can choose from hundreds of product variants within the product models to achieve maximum flexibility for your project.
