Description
The National Instruments NI-9870 C Series Serial Interface Module, with part number 195926A-01, falls under the category of Industrial Communication Interfaces. This module is specifically designed to add serial RS232 ports to CompactRIO frameworks, enhancing their functionality significantly. It features a 4-port RS-232 Interface that provides a reliable means of serial communication.
The power supply required for the NI-9870 is external, ranging from 8 to 28 VDC, making it versatile for various industrial environments. An important aspect of its design is the port isolation, which ensures that each port is isolated from other modules in the system for enhanced safety and performance. The NI-9870 complies with the ANSI/EIA/TIA-232 standard, confirming its adherence to industry standards for serial communication.
Each port on the NI-9870 is equipped with an individual 64 B buffer, facilitating efficient data handling. The module supports baud rates up to 921.6 kbit/s per port, and it can achieve data transfer rates of up to 2 Mbit per second between modules and CompactRIO, making it highly efficient for serial communication tasks. Despite its powerful performance, the power consumption is minimal at 0.5 W (max active), and it even has a sleep mode that reduces power consumption to just 50 µW.
There are two versions of the NI-9870 available: 779891-02 (Non-conformal coated) and 779891-03 (Conformal coated), providing options based on the environmental conditions it will be exposed to. Furthermore, it is compatible with various software including NI-RIO driver, LabVIEW, Visual C#, and Visual C++, ensuring that it can be integrated into a wide range of applications. The module weighs 5.4 oz and is designed to operate in harsh conditions with an operating temperature range of -40 °C to 70 °C and a storage temperature range of -40 °C
