The NI 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 per channel continuous current on all channels and is capable of sinking up to 20 A of current per module (1 A per channel maximum). You can wire NI 9477 channels in parallel to sink up to 20 A of current to a single actuator, motor, or solenoid. The module contains an industry-standard 37-pin D-Sub connector for low-cost cabling to a wide variety of 37-pin accessories from NI or other vendors. It 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 perform only software-timed or static operations when it is installed in an NI CompactDAQ chassis.

The module 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.
