In the latter card, event-driven connections can be established via the COS (change of state) recognition for the digital inputs. Typical areas of use for both cards include automation, test applications, monitoring as well as general data acquisition and control.
Both cards can replace currently available corresponding PCI cards. The software and drivers are downward compatible. Increased efficiency is possible in existing systems and plants via simple exchange. When using the new cards, data transfer is accelerated from 132 MB/sec to 250 MB/sec without any additional work being incurred.
In accordance with industrial requirements, both cards accept a wide range of 5 to 24V input voltage, the high-voltage version PCIe-7432HIR (High Input Range) correspondingly from 12 to 50V. The specified insulation voltage for the PCIe-7432 standard cards is 2500V (RMS). Operation over an ambient temperature range of 0 to 60 °C is permissible at 5 to 95 % relative humidity. Linux and Windows are supported, drivers and SDKs are provided for LabVIEW, MATLAB, C/C++, Visual Basic and Visual Studio.NET.
PCIe-7432 is suited for industrial applications, as a watchdog timer, event counter, frequency counter and generator or pulse generator. All outputs can be used as a current sink up to 500 mA.
PCIe-7256 can be used for the industrial control of digital signals, external relay activation and signal changes, laboratory and automation applications, monitoring switch contacts and limit switches as well as for monitoring tasks.
