The National Instruments 9477 is a 32-channel, 8 μs sinking digital output C Series module for any NI CompactDAQ and CompactRIO chassis. Each channel is compatible with 5 to 60 V signals and features 1,000 Vrms withstand isolation from channel to earth ground. The module can sink up to 625 mA/ch continuous current on all channels and is capable of sinking up to 20 A of current per module. You can wire NI 9477 channels in parallel to sink up to 20 A of current to a single actuator, motor, or solenoid. The NI 9477 contains an industry-standard 37-pin D-Sub connector for low-cost cabling to a wide variety of 37-pin accessories available from NI or other vendors. The NI 9477 also works with industrial logic levels and signals for direct connection to a wide array of industrial relays, solenoids, and motors.

The NI 9477 is a static digital module, so you can use it to perform only software-timed or static operations when installed in an NI CompactDAQ chassis.

The NI 9477 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.
