Description
The 198851D-02L is part of the Single-Board RIO Modules category, specifically the sbRIO-9871 model. This board, manufactured by National Instruments, is designed for serial communication, offering compatibility with both RS485 and RS422 standards. It is identified alternatively by part number 780879-01.
This module provides 4 fully isolated RS485/RS422 ports, allowing for robust communication in industrial environments. It supports a data rate of up to 2 Mbps, with a maximum baud rate of 3.6864 Mbps and a throughput rate of 1.28 Mbps. This high-performance module is designed to meet the needs of demanding applications requiring reliable serial communication.
The board operates with an external supply voltage (Vsup) range of +8V to +28V, accommodating a wide range of power supplies. It is engineered to withstand voltage endurance from -8 VDC to +13 VDC across the RS485/422 port to COM, and it can safely handle ±28 VDC from Vsup to COM, ensuring durability and resilience in various operating conditions.
