### 4. Functionality
The PIO‑16/16L(CB)H functions as a digital I/O expansion interface for portable or embedded systems. It provides opto‑isolated digital input and output channels that can be controlled or monitored through software APIs.

Operation Principle:
- Digital Input: Each input channel detects external DC voltage levels (12–24 V DC). The opto‑coupler converts the external signal into a logic‑level signal for the host system. Negative logic (sink current) is used, meaning the input is ON when the external signal is LOW.
- Digital Output: Each output channel uses an open‑collector transistor circuit capable of sinking up to 100 mA at 35 V DC. The opto‑coupler isolates the output driver from the host logic.
- Interrupt Handling: All input channels can generate interrupts. The 16 input lines are combined into a single interrupt request signal (INTA) to the host.
- Use Cases:
- Industrial equipment control and monitoring
- Data acquisition and machine status logging
- Portable test systems using notebook PCs
- Embedded control in field automation or laboratory environments
- Replacement or extension of PCI‑based digital I/O in mobile systems

Compatibility:
The connector pin assignment and signal configuration are identical to CONTEC’s PCI and PCMCIA equivalents (PIO‑16/16L(PCI)H, PIO‑16/16L(PM)), ensuring software and wiring compatibility across platforms.
