The Logix® 520MD digital positioner offers a host of features that make it stand out among other positioners. This device combines advanced positioning and tuning functions with easy-to-use setup options and powerful diagnostic tools for the ultimate user-friendly experience.
One of the most notable features of the Logix 520MD positioner is its multi-variable gain tuning algorithm. This powerful technology enables the positioner to make large step changes with minimal overshoot, while still ensuring the resolution required to respond to very small step changes. The Auto-tune procedure also cycles the actuator to generate a measured response and select gain values that provide optimal actuator performance.
The Auto-tune function includes a gain modifier selector, which can be used to adjust the calculated gain to achieve the best possible performance outcomes. Additionally, users can easily configure tuning mode and other common settings with the device's DIP switch configuration option.
For custom settings, the tuning sets can be modified using ValveSight™ software or a handheld device. This gives users the flexibility to accommodate a wide range of actuator sizes and types for even greater functionality.
The process of commissioning a control system can be time-consuming and complicated. However, our product offers easy commissioning by providing fast and simple configuration. This streamlines the installation process and allows for faster system integration, saving you both time and money.
In addition to easy commissioning, our product is designed for precise control. Self-calibration and auto-tune functionality allows for accurate and reliable control performance. The adjustable gain selector further enhances precision by optimizing control parameters based on the specific process requirements.
Our product is equipped with industry standard HART communications, providing seamless integration with existing control systems. The low air consumption of our product ensures energy efficiency and reduces operating costs.
The two-stage control design of our product enhances response times and allows for tighter control. This ensures that the process is kept within specified limits, improving product quality and safety.
Standard diagnostic functionality through ValveSight™ software allows for easy troubleshooting and maintenance. This feature enables quick identification of problems, reducing downtime and increasing productivity.
