The NI 9870 is a C Series module manufactured by National Instruments, designed to add four RS232 serial ports to CompactRIO and CompactDAQ systems. Each port is isolated and supports standard RS232 protocol, enabling communication with a wide range of serial devices such as barcode scanners, GPS receivers, and other industrial equipment. The module is engineered for high reliability in industrial environments, offering 250 Vrms channel-to-earth ground isolation. It is compatible with NI LabVIEW and NI-DAQmx software, allowing for easy integration and configuration within measurement and control applications. The NI 9870 is suitable for applications requiring multiple serial connections and robust data communication.
