RTU-BOX Series Real-Time Digital Controller

In 2018, Ritu Utot launched China's first independently developed real-time digital controller, the RTU-BOX, supporting both SIMULINK models and C language development modes. It enables zero-code development, delivering more authentic results verification. Innovation Highlights: Zero-Code Development: Supports Simulink model code generation, enabling one-click program compilation and downloading. More Authentic Results Verification: Unlike conventional hardware-in-the-loop simulation platforms, its underlying framework aligns with mainstream engineering applications, allowing comprehensive validation of research feasibility. High-Speed Low-Level Driver Library: An efficient low-level driver library supports control algorithm execution frequencies of up to 40kHz. Abundant Hardware Resources: Rich hardware resources ensure seamless control of large-scale or multiple devices. Strong EMI Resistance: Robust anti-interference design makes it suitable for industrial-grade electromagnetic environments.
