The National Instruments 9403 is a 32-channel, 7 μs bidirectional digital input/output module for any NI CompactDAQ or CompactRIO chassis. You can configure the direction of each digital line on the NI 9403 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 9403 also features ±30 V overvoltage protection and can source up to 2 mA output current per channel.

When used in an NI CompactDAQ chassis, the NI 9403 can be used as only a static (software-timed) digital input/output module. With the NI 9403 in a CompactRIO chassis, you can use LabVIEW FPGA to program the NI 9403 for implementing custom counter/timers, pulse generation, and much more.

The NI 9933 (or other 37-pin D-Sub connector) is required for use with the NI 9403 module. 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.
