How to control DCL actuator through modbus by vaTestTool_DCL.exe

1.Open vaTestTool_DCL-v1.31.exe. 2.The application will popup a “Connect to” dialog to set the target device id and local computer RS232 port parameters as follow. Choose the COM port which connected to the USB-RS485 connector. Select the modbus baud rate (the default baudrate on DCL actuator now is 9600). Click on “CONNECT”button to connect to the […]

How to choose an actuator?

Determining Specific Valve Drive Parameters For precise fluid control applications, it is essential to define the final valve drive parameters based on factors such as fluid pressure, media type, and control method. This ensures that the selected electric actuator meets the operational requirements. The following parameters should be determined before finalizing the actuator model: Choose […]
