NI 9478

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

Configure Page for: Print PDF Rich Text
  • 16 ch, 50 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 °C to 70 °C operating range
  • Onboard system diagnostics and solenoid health monitoring
  • Designed for solenoid and valve control


The NI 9478 is a 16-channel, 50 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 V 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.

Since your device does not have direct signal connectivity, you need a terminal block to act as an interface between your sensors/signals and your device. A terminal block provides easy access to the inputs and outputs of your hardware.
The chassis provides rugged, modular housing for your controller (if using CompactRIO) and C Series modules. A high-performance backplane in the chassis contains the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your C Series modules. If you are using the NI CompactDAQ platform, then a Personal Computer (PC) will act as the controller of your system. However, if the CompactRIO platform is used then an embedded real-time controller will be used instead.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This device is compatible with a different programming languages depending on the platform used. If you are using the NI CompactDAQ platform then this device is compatible with LabVIEW, C/C++, Visual Basic, and .NET. However, if the CompactRIO platform is used then this device requires the LabVIEW FPGA Module (sold separately), the LabVIEW Real-Time Module (sold separately) and NI-RIO driver software (included with the hardware).
