AO2000 LS25
The AO2000 LS25 is a high-precision analog output module designed for industrial automation systems, specializing in converting digital control signals from PLCs, DCSs, or industrial controllers into stable and accurate analog outputs. It is widely used in process control industries such as chemical processing, water treatment, and food and beverage production, where precise control of actuators like control valves, variable frequency drives, and dosing pumps is essential for maintaining process stability and product quality.
In a chemical processing plant’s reactor temperature control loop, this module receives digital setpoint signals from the DCS (corresponding to a temperature range of 50-300°C) and converts them into 4-20mA analog signals to control the heating valve’s opening. With a linearity error of less than 0.05%, the valve opening is adjusted proportionally to the temperature setpoint, ensuring the reactor temperature changes smoothly at a rate of 2°C per minute. This precise control reduces temperature fluctuations by 25% compared to conventional modules, which is crucial for ensuring consistent chemical reaction rates.
