nnnnOverview
nnnnThe NI 9476 Measurement System includes 32 sourcing digital output channels capable of communicating with a host PC over USB,
nnnnEthernet or 802.11 Wi-Fi.
nnnnMeasurement Bundle Overview
nnnnThe hardware for an NI CompactDAQ single measurement bundle consists of a USB, Ethernet, or 802.11 W-Fi chassis and one of
nnnnthe over 50 NI C Series measurement-specific modules. These small rugged bundles are ideal for portable or distributed
nnnnmeasurements.
nnnnThe chassis controls the timing for the module and handles communication with the PC over the USB, Ethernet, or 802.11 W-Fi bus.
nnnnAdditionally, all NI CompactDAQ chassis include four counter/timers that you can access through a digital I/O module like the NI 9401.
nnnnThe NI 9476 is a C Series 32-channel, 500 us sourcing digital output module. It works in any CompactRIO or NI CompactDAQ
nnnnchassis. Each channel is compatible with 6 to 36 V signals and features 1,000 Vrms withstand isolation from channel to earth ground.
nnnnYou can programmatically monitor the built-in overcurrent and short-circuit protection status of each channel. The NI 9476 can drive
nnnnup to 250 mA/ch continuous current on all channels simultaneously. It contains an industry-standard 37-pin D-SUB connector for
nnnnlow-cost cabling to a wide variety of 37-pin accessories from NI or other vendors. The NI 9476 works with industrial logic levels and
nnnnsignals for direct connection to a wide array of industrial relays, solenoids, and motors.
nnnnThe NI 9476 module is a static digital module, so it can be used only to perform software-timed or static operations when installed in
nnnnan NI CompactDAQ chassis.
nnnnThe NI 9476 requires a 37-pin D-SUB connector such as the NI 9933 accessory kit for direct connectivity. The NI 9933 includes a
nnnnscrew terminal connector with strain relief as well as a D-SUB solder cup backshell for creating custom cable assemblies.
