A software-configurable digital filter prevents false signal recognition due to noise or contact chattering. Filter time constants are adjustable from 0.25 µs to 131.072 ms.

- Driver and Software Support:
Includes Windows and Linux driver libraries (API-PAC(W32), API-DIO(WDM), API-DIO(98/PC), API-DIO(LNX)) and diagnostic utilities. Compatible with Visual Basic, Visual C++, C#, Delphi, and gcc.

- LabVIEW Integration:
Supported by CONTEC’s VI-DAQ library, enabling seamless integration with National Instruments LabVIEW for data acquisition and control applications.

- PCI Bus Compatibility:
Fully compliant with 32-bit, 33 MHz PCI bus specifications. Supports both 3.3V and 5V universal key slots.

- Backward Compatibility:
Connector pin assignments and functions are compatible with the earlier PIO-16/16T(PCI) model, simplifying system upgrades.

- Compact and Lightweight Design:
Dimensions of 121.69 mm (L) × 105.68 mm (H) and a weight of approximately 100 g.

- Regulatory Compliance:
Certified for RoHS, CE, and VCCI standards.
