Description
The product with the part number 191649A-02 (779082-01) falls under the category of PC-based Digital I/O. It is identified by the model PCI-6516. This model, the NI PCI-6516, is designed for industrial applications featuring 32 Source DO, Bank Isolated DO, and comes equipped with NI-DAQ.
One of the key features of the PCI-6516 is its Watchdog Clock. This clock is configurable and ensures that outputs are set to a safe state in the event of a failure or loss of communication. The Watchdog Clock Timeout Period is also configurable, supporting a range up to (232 – 1) × 100 ns, which is approximately seven minutes, allowing for flexible and secure operations.
The Output Lines of the PCI-6516 utilize photocouplers and Darlington arrays, ensuring reliable and isolated signal transmission. The device requires a voltage for Logic High of a minimum of 11 V across input terminals, ensuring clear signal distinction. Conversely, a voltage for Logic Low is defined as 4 V or less. Any voltage within the Invalid Voltage Range, which is between 4 V and 11 V, is considered indeterminate, ensuring robust signal interpretation for industrial applications.
