Specific application
Data acquisition scenario: It can be connected to various sensors or instruments with serial interfaces, such as temperature sensors, pressure sensors, etc. The data collected by these devices is transmitted to the DeltaV system through serial communication for data analysis, processing and storage, and to achieve real-time monitoring of various parameters in industrial processes.

Equipment control scenario: It is capable of controlling external devices such as valves, pumps, motors, etc. through a serial interface. For instance, in the chemical production process, based on the control instructions issued by the DeltaV system, the start and stop of pumps or the opening degree of valves are controlled through this module, thereby precisely controlling the material transportation and process flow.

System communication scenario: It is used to achieve communication between the DeltaV system and other systems or devices that adopt serial communication protocols. For instance, it can be connected to PLC (Programmable Logic Controller), RTU (Remote Terminal Unit), and HMI (Human-Machine Interface) panels, etc., to achieve data interaction and collaborative work among different devices, facilitating centralized management and monitoring of the entire industrial automation system.

Special equipment connection scenarios: It can be connected to printers, barcode readers and other devices. On some industrial production lines that need to print production reports or read material barcode information, it enables communication between related equipment and the DeltaV system, facilitating production management and quality traceability. It can also be connected to remote terminals to achieve remote data transmission and control, and is suitable for some industrial scenarios where equipment is widely distributed and remote monitoring is required.
