National Instruments NI-9478 C Series Digital Module
The National Instruments NI-9478 (Part Numbers: 779940-01 and 779940-02) C Series Digital Module is a 16-channel, 50 μs module that is supported in all CompactDAQ and CompactRIO systems. There are two part numbers for this module with the same specifications. The only difference is part number 779940-02 has conformal coating, while part number 779940-01 does not. The NI 9478 has current limits that the user can program for added system protection, making the module well-suited for solenoid and valve control applications. Depending on how the channels are configured, the NI 9478 module has the capacity to sink up to 16 A of current per module. The digital I/O logic levels of this module are 12V, 24V, 48V.
This module is engineered for users to achieve direct connectivity to a broad spectrum of industrial equipment, including motors, solenoids, and relays. The NI-9478 Digital Module is compatible with LabVIEW FPGA. When this software is installed, it allows the user to establish digital communication protocols, generate pulses, and create user-defined high-speed counter/timers. The NI 9478 features 50 g shock, and 5 g vibration. This C Series Digital Module offers flexibility of use, since the user can move it from CompactDAQ to CompactRIO, and vice versa without needing to modify the module.
The National Instruments NI-9478 C Series Digital Module is also optimized to interact with various industrial logic levels and signals, making it a high-performance device that guarantees high measurement accuracy for applications, and a module that is perfectly suited for industrial deployment.
