NI 780041-01 14-Port CAN Breakout Box with Power and Termination

The NI 780041-01 is a 14-port CAN breakout box that expands connection and analysis capabilities for Controller Area Network bus systems. It provides simultaneous access to multiple CAN devices through seven COMBICON 5-pin screw terminal connectors and seven D-Sub male connectors wired in parallel. The integrated power supply and user-selectable front-panel termination switch (120 Ω, 60 Ω, or none) ensure signal integrity across high-speed, low-speed, single-wire CAN, DeviceNet, and CANopen networks. Desktop or DIN-rail mountable, this 0.64 kg breakout box ships with a protective case.
