Bo mạch PCI16 kênh bộ đếm/tần số với 32 kênh DIO ICP DAS PCI-FC16U CR

The PCI-FC16U is a 32-bit hardware-type high-speed Counter/Frequency board that supports both the 3.3 V and the 5 V Universal PCI bus. The card provides 16 channels that can be individually configured for either frequency measurement or up-counter applications, and can support high-frequency signals up to 250 kHz. The PCI-FC16U board also includes 32 programmable Digital I/O channels.

The PCI-FC16U board includes an onboard Card ID switch that enables the board to be easily recognized via software if two or more boards are installed in the same computer. The pull-high/pull-low resistors allow the DI status to be predefined as either high or low instead of remaining floating if the DI channels are disconnected or interrupted.

The cards support various OS versions, such as DOS, Windows. DLL and Active X control together with various language sample program based on Turbo C++, Borland c++, Microsoft C++, Visual C++, Borland Delphi, Borland C++ Builder, Visual Basic, C#.NET, Visual Basic.NET and LabVIEW are provided in order to help users to quickly and easily develop their own applications.

Max. Counter/Frequency 1 Hz ~ (typically ) 250 kHz (both counter mode and frequency mode)
where 250 kHz is calculated as followings:
Supposed that duty cycle = 50%, refer to Minimum Pulse Duration of High Level, we have pulse period = 2 μs x 2 = 4 μs, which is 250 kHz as a max.Refer to Min. Pulse Duration of High Level, Max. Frequency is highly affected by duty cycle.
Frequency Accuracy ± 0.4 %
