National Instruments NI-9862

The National Instruments NI-9862 C Series CAN Interface Module (Part Number: 781639-01) is a high-speed Controller Area Network (CAN) interface designed for applications requiring rapid manipulation of multiple CAN frames and signals in real-time. Optimized for automated control, bus monitoring, quick control prototyping, and hardware-in-the-loop simulation, the NI-9862 integrates seamlessly with the NI-XNET driver, facilitating a wide range of application environments. This module is equipped with a fully functional, isolated CAN port that complies with the CAN 2.0B standard and supports both 11-bit and 29-bit identifiers, utilizing a Bosch DCAN CAN controller.

The module features an NXP TJA1041AT High-Speed CAN transceiver that adheres to the ISO 11898 standard and can accommodate baud rates up to 1 Mbps. Weighing approximately 144 grams (5.0 ounces), the NI-9862 is lightweight and portable, with a maximum power consumption of 1 W in active mode and a thermal dissipation of 1.25 W at 70 °C, ensuring efficient operation. It supports a voltage range for port-to-COM connections of -27 V DC to +40 V DC and a supply voltage (Vsup) of +9 V DC to +30 V DC, maintaining strict compliance with safety voltage standards. The isolation features ensure continuous port-to-earth ground isolation of 60 V DC and withstand isolation of 500 V RMS, validated by a 5-second dielectric withstand test.

The NI-9862's versatility allows it to support various applications simultaneously, enabling additional data acquisition measurements on the same NI CompactDAQ hardware platform while managing CAN frames at high speeds. Furthermore, it facilitates embedded monitoring and low-level FPGA control within the same NI CompactRIO chassis, making it an invaluable component for modern industrial automation and control systems.
