The Logix® 520MD Series digital positioner is a powerful tool that offers advanced positioning and tuning capabilities, as well as easy setup and intuitive diagnostic tools. It features a multi-variable gain tuning algorithm, which allows the positioner to efficiently handle large step changes while still maintaining precision for smaller adjustments. This algorithm helps to minimize overshoot, thereby improving overall performance. One key feature of the Logix 520MD is its Auto-tune procedure, which activates the actuator to generate a measured response, automatically selecting gain values that optimize actuator performance. In addition, the Auto-tune function includes a gain modifier selector, which enables users to fine-tune performance by adjusting calculated gain. This makes it easy to achieve optimal results for a variety of different applications. To ensure maximum flexibility, the Logix 520MD can be easily configured using DIP switches for tuning mode and other standard settings. For more specialized needs, tuning sets can be customized via a handheld device or ValveSight™ software, making it adaptable to various actuator sizes and types. Whether you're a seasoned professional or new to the field, the Logix 520MD is an excellent choice for high-performance digital positioners.
The Logix 520MD Series digital positioner guarantees simple commissioning with a quick and straightforward configuration process. This digital positioner is equipped with self-calibration and an auto-tune function, along with an adjustable gain selector for optimized performance. Using industry-standard HART communication, it provides low air consumption and a two-stage control design for faster response times and tighter control.
Furthermore, to enhance overall functionality, ValveSight™ software provides standard diagnostic capabilities. This digital positioner solution delivers reliable operation and increased functionality to ensure precision and accuracy in your processes.
