Description
The NI-9474 is a high-performance C Series Digital I/O module, designed to cater to a wide range of industrial and laboratory applications. It features part numbers 779003-01 and 783908-01, highlighting its versatility in connectivity options. This module is specifically engineered for applications requiring 24 V logic levels and rapid response times, with an impressive Update Rate Maximum of 1 μs.
With 8 Digital Output Channels, the NI-9474 is capable of handling multiple outputs simultaneously, making it an ideal choice for complex automation tasks. It supports both 12 V and 24 V digital I/O, providing flexibility in interfacing with various devices. Furthermore, its Channel-to-Earth Isolation of 250 Vrms, CAT II, ensures robust protection against voltage spikes and surges, enhancing the reliability and safety of your system.
The module’s Output Voltage Capacity ranges from 5 VDC to 30 VDC, accommodating a broad spectrum of actuators and indicators. Each channel can deliver a Continuous Output Current of 1.0 A, sufficient for driving most standard loads. Additionally, the NI-9474 boasts an Output Impedance of 0.07 Ω to 0.13 Ω, minimizing voltage drop and power losses across the outputs.
Connectivity is facilitated through either a 10-position Screw Terminal (part number 779003-01) or a 10-position Spring Terminal (part number 783908-01), offering ease of installation and maintenance. While the module is not Conformal Coated, it is designed to withstand typical industrial environments. For optimal performance and safety, it is recommended to use the NI-9927 Backshell Connector Kit for Screw Terminal configurations, or the NI-9981 Backshell Connector Kit for Spring Terminal configurations.
