National Instruments Corporation NI 9871E 4-PORT RS422/485 SERIAL BOARD-ONLY W/4 10P10C-DE9 CABLES
The NI 9871E is a 4-port serial module designed by National Instruments for use with CompactRIO and CompactDAQ systems. It provides four independent RS422/RS485 serial ports, enabling high-speed, reliable communication with industrial devices such as sensors, actuators, and controllers. The module supports both full-duplex and half-duplex modes, and each port is isolated for robust performance in noisy environments. The 'board-only' version (PN: 780879-02) includes four 10P10C-to-DE9 cables for convenient connectivity. The NI 9871E is ideal for applications requiring multiple serial connections and is engineered for seamless integration with NI's modular platforms.
