The NI-9853 is a high-speed CAN (Controller Area Network) interface module manufactured by National Instruments (NI) for use in CompactRIO systems. It has two 9-pin male DSUB connectors that CAN be used to connect to the CAN bus. Each port has two common pins (COM) that are internally connected to the module's isolated reference ground and used as a reference ground for CAN_H and CAN_L. The user CAN connect the reference ground of the CAN bus (also called CAN_V-) to one or all of the COM pins. In addition, each port comes with an optional shield pin (SHLD), which can be connected to enhance signal integrity and EMC performance in noisy environments.
The NI-9853 is ideal for developing low-level FPGA-based control and triggering applications, especially when using the LabVIEW FPGA module for byte-level manipulation of CAN frames. It is also particularly suitable for use in hazardous environments, including Class I, Division 2, Groups A, B, C, D, T4 and other environmental grades. When installing NI-9853 in these environments, specific safety guidelines are required to ensure the safety of personnel and the proper operation of equipment.
Overall, the NI-9853 is a powerful and adaptable high-speed CAN interface module for a variety of industrial automation and embedded computing applications that require high-speed data transfer and control.
The NI-9853 is a high-speed CAN (Controller Area Network) interface module designed for CompactRIO systems. It has a wide range of applications, especially for automotive and industrial applications.
In automotive applications, the NI-9853 CAN be used to monitor the CAN bus in the vehicle, reading and writing values from CAN devices such as electronic control units and brakes. In addition, it can also communicate with other devices in the car to achieve various functions of vehicle control and monitoring.
In industrial applications, the NI-9853 CAN be used as a high-performance CAN interface to communicate with industrial equipment such as motion control drives and motors. Through its high-speed data transmission capability, real-time monitoring and control of industrial equipment can be achieved to improve production efficiency and equipment reliability.
In addition, because the NI-9853 is integrated with NI's reconfigurable I/O (RIO) technology, it can also be used to build on-board measurement and control platforms, providing the industry's highest performance solution.
