National Instruments CAN Breakout Box Terminal Block

The National Instruments CAN Breakout Box (Part number 780041-01) is a high-performance terminal block that provides interfacing for multiple Controller Area Network devices or PC interfaces. The breakout box provides easy connections between high-speed, low-speed, and single-wire CAN with its 14-port configuration, thus being applied in a wide variety of applications, including DeviceNet and CANopen. The CAN breakout box makes integrating several devices easier while sustaining communication and system stability.

The CAN breakout box features seven D-Sub male connectors with a CiA-DS-102 pinout and seven COMBICON five-pin removable screw-terminal connectors, providing versatile connection options. All 14 ports on the CAN breakout box are wired in parallel, enabling the connection of multiple devices simultaneously to the NI CAN hardware. Due to this parallel configuration, it is highly suited for such a complex setup where multi-device communication is required, especially in an industrial and testing environment.

On an integrated power supply-if available on the CAN breakout box-power is fed on an input pin, often labeled as "V+." Some kinds of CAN transceivers require this to operate properly. This feature saves the deployment in both laboratories and industries because using an integrated power supply rules out many other ways of providing a power source. In addition, the CAN breakout box front panel features a user-selectable termination switch for 120 Ω, 60 Ω, or no termination, which can finely tune a network to provide the capability of ensuring signal integrity.

The CAN breakout box is compatible with all National Instruments CAN cables, interfaces, and accessories, making it easy to integrate into existing setups. For maximum flexibility, the CAN breakout box supports both desktop use and DIN rail mounting for usage in test fixtures, control cabinets, and other demanding installations; its design is compact and robust.

Engineered for performance and versatility, the National Instruments CAN Breakout Box is a valuable tool for managing multi-device CAN systems. The CAN breakout box provides efficient, dependable solutions for industrial automation, testing, and network integration tasks with features such as parallel port wiring, onboard power, and configurable termination. This CAN breakout box is a reliable choice for engineers seeking a robust and flexible connectivity tool.
