The Logix® 520MD digital positioner is an advanced device that offers exceptional positioning and tuning functions, combined with convenient setup options and powerful diagnostic tools. The positioner is equipped with a multi-variable gain tuning algorithm, which means it can perform large step changes with minimal overshoot, while still having the resolution to respond quickly to small step changes.
One of the most impressive features of the Logix 520MD positioner is its Auto-tune procedure. When activated, this function cycles the actuator, producing a measured response which it then uses to select gain values that lead to optimal performance. In addition to this, the Auto-tune function comes with a gain modifier selector, which gives users the ability to either increase or decrease the calculated gain in order to achieve optimal performance. This flexibility makes the Logix 520MD the perfect choice for a variety of applications.
Another key advantage to the Logix 520MD is its easy DIP switch configuration. The device provides a simple and streamlined way to configure tuning modes and other commonly used settings. In addition to this, for applications that require custom settings, the tuning sets can be modified using a handheld device or with ValveSight™ software. This means that the Logix 520MD can be customized to work with a wide range of actuator sizes and types, making it a truly versatile choice for countless applications.
Easy commissioning is made possible with our product's fast and simple configuration process. This feature ensures that even those without extensive technical knowledge can easily set up the product.
Our product is also equipped with self-calibration and auto-tune functions with an adjustable gain selector. This ensures that the product's performance is optimized at all times, even in changing conditions.

Power generation is an essential part of modern society. There are various sources and technologies used to generate power, including conventional steam, combined cycle, concentrated solar power (CSP), biomass & MSW, and geothermal. Conventional steam systems utilize steam turbines to produce electricity from burning fossil fuels. Combined cycle technology involves using gas and steam turbines in a combined system to increase efficiency and lower emissions. CSP uses mirrors or lenses to capture and focus the sun's energy onto a receiver, which heats a fluid to generate power. Biomass & MSW systems burn organic materials to produce energy, and geothermal systems harness the heat from the earth's crust to generate electricity.
The chemical industry plays a critical role in producing a wide range of products and materials used in everyday life. Basic chemicals include both organic and inorganic compounds, such as acids, bases, and salts. Specialty chemicals, including fine and consumer chemicals, are used in a variety of industries, including cosmetics, electronics, and pharmaceuticals. The production of biofuels involves using organic matter, such as crops and animal waste, to produce renewable energy. The pharmaceutical industry produces drugs to treat a range of illnesses and diseases. Petrochemicals are used in a variety of products, from plastics to synthetic fibers.
Water is a precious resource and is vital to sustaining life. Water management involves managing water resources to ensure an adequate supply for drinking, irrigation, and industrial use. Wastewater treatment helps to clean and filter used water so that it can be reused or safely returned to the environment. Agriculture and irrigation systems utilize water to produce crops and ensure adequate water supplies for farming. Flood control systems help to prevent or reduce the damage caused by floods and other water-related disasters.
The oil and gas industry is responsible for exploring, extracting, and processing fossil fuels. Upstream exploration and production involve identifying and drilling wells to extract oil and gas from the ground. Midstream transportation involves moving these resources to processing plants and distribution centers. Downstream processing involves refining crude oil into usable products, such as gasoline and diesel fuel.
General industries encompass a broad range of industries, including pulp and paper, steel and primary metals, food and beverage, corn wet milling and ethanol, and other industries. The pulp and paper industry produces a variety of paper products used in everyday life. Steel and primary metals are used in construction projects, automobiles, and other machinery. The food and beverage industry produces food and drink products, while corn wet milling and ethanol involve extracting starch from corn and converting it into fuel and other products.
Mining involves extracting valuable minerals and other resources from the earth. This includes precious metals, such as gold and silver, as well as industrial minerals used in construction and manufacturing. Environmentally sustainable mining practices are crucial to protecting the environment and ensuring a responsible use of natural resources.
