Description
The National Instruments NI-9881 C Series CANopen Interface Module, with a part number of 195433C-81L (781673-01), belongs to the category of Industrial Communication Interfaces. This model, NI-9881, is specifically designed for various applications including industrial automation, maritime electronics, off-road vehicles, medical equipment, building automation, and public transportation. It features 1 CANopen channel which allows for efficient communication within these applications.
The module supports a maximum baud rate of up to 1 Mbits/s, ensuring fast data transfer rates that can meet the demands of high-speed communication requirements in complex systems. Connectivity is facilitated through one 9-pin, D-Sub male connector, providing a reliable and secure physical connection for data transmission.
Additionally, the NI-9881 module is equipped with two common pins that are connected to the isolated reference of the module, enhancing its safety and reliability in various operating environments. An optional shield pin (SHLD) is also available, offering further protection against external electromagnetic interference, thus ensuring stable and uninterrupted communication.
One of the notable features of this module is its software-selectable bus termination. This feature allows for the easy configuration of 120 Ω termination resistors between CAN_L and CAN_H, which is essential for the integrity and reliability of communication in CAN networks. This flexibility in configuration makes the NI-9881 an adaptable solution for a wide range of industrial communication needs.
