Description
The 198850D-03L is a robust component in the category of Industrial Communication Interfaces, specifically the model NI-9870. This module assembly is designed for serial communications, providing RS232 interface with 4 ports, accommodating the needs for multiple serial connections in industrial environments. The NI-9870 is conformal coated, ensuring its durability and reliability in harsh conditions.
Each of the four ports is equipped with individual 64 B buffers, facilitating efficient data handling and transmission at baud rates up to 921.6 kbit/s per port. This high-speed data transfer capability is supported by an external power supply requirement of 8 to 28 VDC, with a minimal power consumption of 0.5 W in its maximum active state, and an impressive 50 μW during sleep mode, highlighting its energy efficiency.
The module includes a PC-MF4-PT cable, ensuring immediate connectivity and operational capability out of the box. It supports a maximum cable length of 250 pF equivalent, optimizing signal integrity over distances. Compatibility with software such as NI-RIO driver, LabVIEW, Visual C#, and Visual C++ makes integration into existing systems seamless, offering versatile application possibilities.
With a weight of 5.4 oz and designed to operate within a temperature range of -40 °C to 70 °C, and store from -40 °C to 85 °C, it is built to withstand challenging industrial environments. Its robustness is further evidenced by a vibration tolerance of 5 grms, 5g (10 to 500 Hz), ensuring reliable performance under mechanical stress.
Moreover, it offers conformal coated versions with part numbers 779891-03 (Yes) and 779891-02 (No), allowing users to choose based on their specific environmental protection needs. This detailed specification underlines the NI-
