### 4. Functionality

Operating Principle:
The PIO‑16/16RY(PCI) interfaces digital control signals between a PC and external devices. Input channels detect ON/OFF states of external current‑driven devices (switches, sensors, transistor outputs). Output channels drive loads such as relays, LEDs, or PLC inputs through isolated semiconductor relays.

Use Cases and Applications:
- Industrial automation and process control
- Machine status monitoring and alarm systems
- Laboratory instrumentation and data acquisition
- PLC or sensor interfacing
- Relay control and signal switching in test benches

Compatibility:
- Operating Systems: Windows 7/Vista/XP/2000/Server 2003, Linux (Red Hat, TurboLinux)
- Programming Languages: Visual Basic, Visual C/C++, C#, Delphi, C++ Builder, gcc
- Software Tools: API‑PAC(W32), API‑DIO(LNX), VI‑DAQ for LabVIEW

Interrupt Handling:
All 16 input channels can trigger interrupts. The board consolidates them into a single INTA output to the PCI bus. Software can select the trigger edge (rising or falling).

Digital Filtering:
A programmable digital filter (0–131.072 ms) suppresses noise and contact bounce. The filter applies globally to all input channels.

Isolation and Safety:
Optocoupler isolation ensures electrical separation between the PC and external circuits, protecting against surges and ground loops.
