Main Features and Advantages
Dual – Channel CAN Communication
The NI NI-9505 stands out with its dual – channel CAN interface, allowing for simultaneous communication on two independent CAN networks. This feature is extremely useful in complex systems where multiple CAN – based subsystems need to be monitored and controlled separately. For example, in a large – scale industrial plant, one channel can be dedicated to the communication of production line machinery, while the other can handle the monitoring of safety – critical systems. The dual – channel design increases the module’s versatility and enables more efficient management of CAN – based communication tasks.
High – Speed Data Transfer
With a data rate of up to 1 Mbps, the NI-9505 ensures fast and efficient data transfer within CAN networks. In applications where real – time data is crucial, such as in automotive engine control systems or high – speed manufacturing processes, this high – speed capability allows for quick response times and seamless coordination between devices. It enables the transmission of large amounts of data in a short period, ensuring that the connected systems can operate at optimal performance levels.
Robust Isolation and Error Handling
The module features 2500 V rms galvanic isolation, providing excellent protection against electrical noise, ground loops, and voltage spikes. This isolation not only enhances the reliability of the communication but also safeguards the connected devices from potential electrical damage. Additionally, the NI NI-9505 is equipped with comprehensive error – handling mechanisms. It can detect and report various CAN – specific errors, such as bit errors, stuff errors, and CRC errors, ensuring data integrity and enabling quick troubleshooting in case of communication issues.
Large Message Buffer
The NI-9505 comes with a generous message buffer of 128 transmit and 128 receive buffers. This large buffer capacity allows the module to handle a high volume of messages without data loss, even during peak communication periods. It ensures smooth data flow and reduces the likelihood of buffer overflows, which can cause communication failures. This is especially beneficial in applications with a high message traffic density, such as in complex automotive networks or large – scale industrial automation systems.

Application Field
The NI NI-9505 finds extensive applications across multiple industries. In the automotive industry, it is widely used for in – vehicle networking, diagnostic systems, and powertrain control. It enables communication between different electronic control units (ECUs), such as the engine control module, transmission control module, and anti – lock braking system. This allows for coordinated operation of vehicle systems, improved performance, and easier diagnostic and maintenance.
In industrial automation, the NI-9505 plays a crucial role in connecting and controlling CAN – based devices on the factory floor. It can be used to integrate programmable logic controllers (PLCs), robotic arms, sensors, and actuators into a unified network, enabling seamless data exchange and precise control of manufacturing processes. This results in increased productivity, enhanced quality control, and reduced downtime.
The module is also valuable in the aerospace and defense sectors, where it can be used for communication between different avionics systems and subsystems. It ensures reliable data transfer in harsh environments, facilitating the operation and monitoring of critical systems in aircraft and spacecraft. Additionally, in research and development, the NI NI-9505 can be used to develop and test CAN – based communication protocols and systems, providing researchers with a powerful tool for innovation.
