Description
The part number for this product is 191649B-02, with an alternate number of 779082-01. It falls under the category of PC-based Digital I/O, specifically the model PCI-6516. This model is described as the NI PCI-6516 Industrial 32 Source DO, Bank Isolated DO & NI-DAQ, which incorporates a variety of high-end features for industrial applications.
One of the key features of the PCI-6516 is its Watchdog Clock. This safety feature is equipped with a configurable timeout that can be set up to (232 – 1) * 100 ns, which is approximately 7 minutes. In the event of a failure, the Safe State Outputs are enabled by the Watchdog Clock, ensuring the safety and integrity of the system’s operations.
The output lines of the PCI-6516 consist of Photocouplers and Darlington arrays. These components are crucial for providing isolation and amplifying the signals, respectively. As for the input logic levels, the voltage range for a logic high is defined as a DC voltage of at least 11 V, while for a logic low, it is DC voltage of 4 V or less. Any voltage between 4 V and 11 V is considered as an invalid voltage range.
Furthermore, the power supply for the output lines is quite versatile, allowing for a range of 5 V to 30 V. This flexibility in voltage input ensures that the PCI-6516 can be integrated into a wide array of industrial environments and applications, making it a highly versatile and essential component for PC-based digital I/O operations.
