### 4. Functionality

The PCI‑7433ALC functions as a 64‑channel isolated digital input interface card for PCI‑based industrial PCs. Each input channel is optically isolated from the host system, allowing safe connection to external AC or DC signals without electrical interference or ground potential differences.

Operating Principle:
- Each input channel uses an optocoupler to detect the presence of an AC or DC voltage signal.
- The card converts the external signal into a logic‑level input readable by the host computer.
- Non‑polarity design allows connection of AC signals without concern for polarity.
- Two dedicated interrupt channels (0 and 1) can trigger software events for real‑time monitoring.

Typical Use Cases:
- Industrial automation and process control systems.
- Machine status monitoring and event logging.
- AC signal detection for relay or contact monitoring.
- Laboratory data acquisition and test automation.
- Integration with Opto‑22 or similar I/O racks for modular expansion.

Compatibility:
- Compatible with standard PCI slots in desktop or industrial PCs.
- Works with ADLINK terminal boards (DIN‑100S‑01) and cables (ACL‑102100‑1).
- Supported by ADLINK’s NuDAQ/NuIPC software suite and PCIS‑DASK driver library.
