Comparaison des performances de résistance aux interférences : 4-20mA VS. 2-10V
In the application of electric actuators’ anti-interference performance, the 4-20mA analog signal significantly outperforms the 2-10V analog signal. Why is this the case? 2-10V Signal Analysis Anti-interference Diagram for 2-10V Signal (DCL Huayi Intelligent Control) As shown in the diagram above: When using 2-10V, due to the higher input resistance on the module (R=34K), the […]

An increasing number of industrial control systems are deploying field buses to control more sensors and actuators. As a key actuator in fluid control processes, electric actuators are commonly used in industrial applications. The most frequently used bus systems for electric actuators include Modbus, CAN, Profibus, DeviceNet, Foundation Fieldbus, HART, and Ethernet. Common Bus Systems […]
EN15714-2 Classification des commandes d'actionneurs électriques (service)
Control Duty Classifications: Class A: ON-OFF Type (On/Off) Function: The actuator is required to drive the valve through its entire stroke from fully open to fully closed (and vice versa). Typical Use: Applications where valves are either fully open or fully closed. Class B: Fine-Tuning/Positioning Adjustment Type Function: The actuator occasionally moves the valve to […]
Quand choisir un actionneur de contrôle de processus ?
Application Background of Process Control Actuators In many process control systems, it is necessary to achieve highly accurate and consistent control of the flow rate of liquids or gases through an automated control system (PLC/DCS). Due to the high precision required, such systems often need to make continuous and precise small adjustments to control valves […]
