Description
85 °C
The NI-9871 is a serial module characterized by its part number 198851A-01L, designed for robust and efficient communication. This module features 4-Port, RS485/RS422 interfaces, making it versatile for various industrial applications. It boasts a maximum baud rate of 3.6864 Mbps, allowing for rapid data transmission across systems.
One of the notable specifications of the NI-9871 is its data line ESD protection, which is rated at ±15 kV, offering significant protection against electrostatic discharges. This ensures the longevity and reliability of the module in electrically noisy environments. Furthermore, it supports a maximum cable length of 1.2 km (4,000 ft.), enabling long-distance communications without signal degradation.
In terms of power efficiency, the module’s power consumption is impressively low, with a maximum of 0.5 Watts in active mode and merely 50 μWatts in standby/sleep mode. It requires a power supply of +8 to +28 VDC, consuming up to 3.5 Watts at its peak. This makes the NI-9871 not only powerful but also energy-efficient.
The module ensures safety and reliability with its port-to-earth ground isolation of 60 VDC continuous, and it can withstand isolation up to 1000 Vrms. Connectivity is facilitated through a four-position, female pigtail and a DB-9 male front panel connector, offering flexibility in connections.
With a weight of 5.4 oz., the NI-9871 is relatively lightweight and portable. It is designed to operate within a temperature range of –40 to 70 °C and can be stored in temperatures ranging from –40 to 85 °C, ensuring its performance in extreme conditions.
