NI 9478

16 Ch, 7 µs, Up to 50 V Sinking Digital Output

  • 16 ch, 7 µs digital output module
  • Programmable current limits for customizable system protection
  • Up to 1.2 A per channel (all 16 channels) or 5 A for a single channel
  • -40 to 70 °C operating range
  • Onboard system diagnostics and solenoid health monitoring
  • Ideal for solenoid and valve control and high-frequency PWM operations

The NI 9478 is a 16-channel, 7 µs, sinking digital output C Series module with programmable current limits, which provide customizable system protection that is ideal for solenoid and valve control applications. Each channel is compatible with 5 to 50 V signals and features 1,000 Vrms withstand isolation from channel to earth ground. The NI 9478 can sink up to 16 A of current per module, depending on channel configuration. It uses an industry-standard 37-pin D-Sub connector for low-cost cabling to a wide variety of 37-pin accessories from NI or other vendors. The module also works with industrial logic levels and signals for direct connection to a wide array of industrial relays, solenoids, and motors.

The NI 9478 requires a 37-pin D-Sub connector or cable such as the NI 9933 accessory kit for direct connectivity. The NI 9933 includes a screw-terminal connector with strain relief as well as a D-Sub solder cup backshell for creating custom cable assemblies.

What is Conformal Coating?

Conformal coatings are specially formulated thin film materials that are applied directly to circuit boards or circuit card assemblies (CCAs). These films provide environmental protection for components and circuitry. The thin film materials used for conformal coating are normally applied using a process of dipping or spraying the CCA with a liquid or resinous material. As the material dries, it forms a resilient coating that can protect against moisture, mold, dust, corrosion and other environmental stresses.
