Siemens 6DR5020-0NG00-0AA0
Siemens 6DR5020-0NG00-0AA0 is an intelligent electrical valve positioner that combines advanced microprocessor technology and piezoelectric valve control technology to provide a high-precision and reliable solution for industrial automation process control. The following is a detailed introduction to the product:
1. Product Overview
Model: 6DR5020-0NG00-0AA0
Brand: Siemens
Type: Intelligent electrical valve positioner
Application fields: Widely used in automated control systems in chemical, petrochemical, power plants, papermaking, glass, water treatment, food and pharmaceutical, offshore platforms and other industries.
2. Working principle
Siemens 6DR5020-0NG00-0AA0 uses a microprocessor to compare the given value and position feedback. When a deviation is detected, the microprocessor will output an electronic control instruction to the piezoelectric valve. The piezoelectric valve adjusts the air flow entering the actuator air chamber according to the instruction, thereby controlling the opening of the valve. The microprocessor control strategy includes a five-step switching program and the output of continuous signals or continuous pulses based on the size and direction of the deviation to achieve precise valve positioning.
3. Product features
High-precision control: Using advanced microprocessor technology and piezoelectric valve control technology to achieve high-precision valve positioning.
Automatic initialization: With automatic initialization function, it can automatically adjust the zero position and stroke range, simplifying the installation and debugging process.
Easy to operate: Using three buttons and two-line LCD display, the simple operation and programming interface makes it convenient for users to perform on-site operation and maintenance.
Low gas consumption: gas is only consumed during action, and gas consumption is negligible during steady-state operation, reducing operating costs.
Rich diagnostic functions: Able to report multiple information on changes in control valves and actuators, helping users find and solve problems in a timely manner.
