Description
The National Instruments NI-9881 C Series CANopen Interface Module, with Part Number 781673-01, is a high-performance module designed for industrial automation applications. Manufactured by National Instruments, this module supports a CANopen interface and is equipped with one CANopen channel capable of communication speeds up to 1 Mbits/s.
The NI-9881 features a robust connection through its one 9-pin, D-Sub male connector, and includes two common pins that are internally connected to the module’s isolated reference, ensuring stable and reliable operation. The presence of an optional shield pin (SHLD) allows for improved electromagnetic compatibility (EMC) performance and signal integrity in challenging environments.
Flexibility in bus configuration is provided by software-selectable bus termination, which includes 120 Ω termination resistors that can be activated through API calls. This module is adept at handling both PDOs (Process Data Objects) and SDOs (Service Data Objects), adhering to the CiA DS 301 standard, which makes it suitable for a wide range of industrial applications requiring robust and precise data communication.
