Description
The NI-9870 is a part of the Industrial Communication Interfaces category, bearing the part number 198850C-03L. This model is designed for robust and efficient serial communication, featuring 4 RS232 ports which are capable of handling up to 921.6 kbit/s per port in baud rates, ensuring high-speed data transfer capabilities. The module is equipped with a conformal coating, with part numbers 779891-02 for the non-coated version and 779891-03 for the coated version, enhancing its durability and suitability for challenging industrial environments.
Regarding power requirements, the NI-9870 operates with an external power supply ranging from 8 to 28 VDC, while maintaining a low power consumption of 0.5 W in its maximum active state and just 50 μW in sleep mode. This efficiency does not compromise its performance, as the module adheres to ANSI/EIA/TIA-232 serial standards and supports a maximum data rate of 2 Mbit/s, with a buffer size of 64 B per port. The device is capable of operating over long distances with a maximum cable length of 250 pF equivalent, ensuring reliable communication over extended ranges.
The NI-9870 is built to withstand severe temperature conditions, offering an operating temperature range of -40 °C to 70 °C and a storage temperature range starting from -40 °C. This wide temperature range makes it exceptionally suitable for industrial applications that may expose the device to extreme conditions. The NI 9870, 4 Port RS232 Serial Module, with its conformal coating, is thus an ideal solution for robust and reliable serial communication in demanding industrial settings.
