Description
The NI-9871 is a versatile and powerful module with part numbers 779892-01, 779892-02, and 779892-03. It features four RS485/RS422 ports, making it an ideal choice for applications requiring high-speed and reliable serial communication. This module is specifically designed to be programmed using the LabVIEW Full Development System for Windows, offering a robust environment for developing complex applications.
One of the standout features of the NI-9871 is its maximum baud rate of 3.6864 Mbps, allowing for fast data transmission over serial connections. Additionally, it boasts ESD protection of ±15 kV on the data line, ensuring the integrity of data in electrically noisy environments. The module supports a maximum cable length of 1.2 km (4,000 ft.), enabling communication over long distances without signal degradation.
In terms of power efficiency, the NI-9871 has a maximum active power consumption of 0.5 Watts and can go as low as 50 µWatts in standby or sleep mode. It requires an external power supply of up to 3.5 Watts from a +8 to +28 VDC source. The module also offers excellent isolation properties, with 60 VDC continuous port-to-earth ground isolation and the ability to withstand up to 1000 Vrms.
Connectivity is facilitated through a four-position, female pigtail and a DB-9 male front panel connector, providing flexibility in connecting to various types of equipment. Despite its robust features, the module is compact, weighing just 5.4 oz. It is designed to operate in extreme temperatures, ranging from –40 to 70 °C and can be stored in temperatures ranging from –40 to 85 °C. The humidity range for both operating and storage conditions is 10 to 90% RH (non-condensing), with a broader range of 5 to 95% RH accommodating various environmental conditions.
Finally, the NI-9871 is built to withstand harsh environments, capable
