Description
The Part Number 780922-02 refers to the sbRIO-9870, a product developed by National Instruments. This product falls under the category of C Series Serial Interface Module and is specifically designed for compatibility with NI CompactRIO systems. It features 4 RJ-50 receptacles/ports for RS232 devices, making it highly suitable for applications requiring serial communication.
The sbRIO-9870 is described as an NI 9870E 4-PORT RS232 Module Board-Only and comes with 4 10P10C-DE9 cables to facilitate connection to various devices. Each of the four ports on the module has a buffer size of 64 B, ensuring efficient data handling during communication processes. The module supports standard communication parameters such as start bit, stop bit, and flow control settings, enabling versatile configurations according to the needs of specific applications.
An external power supply is required for the module’s operation, with a voltage supply (Vsup) specification. The RS232 signal voltage range supported by the device is ±8 V, and it can handle baud rates of up to 921.6 kbps, providing fast and reliable data transmission. The sbRIO-9870 can operate in two modes: active mode and sleep mode. In active mode, the power consumption is 0.5 W, while in sleep mode, it dramatically reduces to 50 µW, offering energy efficiency during periods of inactivity.
The module is designed with robust protection features, including a voltage withstand capacity of ±25 V for receive signals to COM, ±13.2 V for transmit signals to COM, and ±28 V between Vsup and COM. Additionally, it provides an isolation overvoltage protection of 1000 Vrms between each port and earth ground, ensuring the safety
