The NI 9403E is a board-only, 32-channel, 7 μs, bidirectional digital input/output module for any NI Single-Board RIO device. You can configure the direction of each digital line on the NI 9403E for input or output. 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 NI 9403E also features ±30 V overvoltage protection and can source up to 2 mA output current per channel.
You can use the NI LabVIEW FPGA Module to program the NI 9403E for implementing custom counter/timers, pulse generation, and more.
The NI 9403E module requires the NI 9933 (or other 37-pin D-Sub connector). 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.
