Configure Page for: Print PDF Rich Text
  • 4-channel, 55 ns high-speed digital I/O
  • LVTTL sinking/sourcing digital I/O
  • BNC connectivity for quick connections
  • Bidirectional, configurable by line with shift-on-the-fly capability
  • -40 to 70 °C operating range
  • Hot-swappable operation


The NI 9402 is a 4-channel, 55 ns bidirectional digital input module for any NI CompactDAQ or CompactRIO chassis. You can configure the direction of the digital lines on the NI 9402 for input or output on a per-channel basis. With reconfigurable I/O (RIO) technology (CompactRIO only), you can use the NI LabVIEW FPGA Module to program the NI 9402 for implementing custom, high-speed counter/timers; digital communication protocols; pulse generation; and much more. Each channel is compatible with 5 V/TTL signals and features 1,000 Vrms transient isolation between the I/O channels and the backplane.

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).
