### 2. Key Features

- Opto-Isolated I/O Channels:
64 opto-coupler isolated inputs (current sink compatible) and 64 opto-coupler isolated open-collector outputs (current sink type). Each group of 16 channels shares a common terminal, allowing multiple external power supplies.

- Voltage and Logic Compatibility:
Supports 12–24VDC input/output operation with negative logic (data “0” = High, “1” = Low).

- High Noise Immunity:
Complete opto-coupler isolation between the PC bus and I/O interfaces ensures excellent noise performance and protection against ground loops.

- Interrupt Functionality:
Up to 16 input channels (I-00 to I-17) can be configured as interrupt request signals. Interrupts can be triggered on rising or falling edges and enabled/disabled per bit.

- Digital Input Filtering:
Built-in digital filter prevents false signal recognition due to noise or contact chattering. Filter time constants are software-configurable from 0.25 µs to 131.072 ms.

- Output Protection:
Each output circuit includes a Zener diode (RD47FM or equivalent) for surge suppression and an overcurrent protection circuit per 8-channel block.

- Fast Response:
Input and output response times are both 200 µs (max), suitable for high-speed control and monitoring.

- Software Support:
Includes Windows and Linux driver libraries (API-PAC(W32), API-DIO(WDM), API-DIO(LNX)) and diagnostic utilities.
Compatible with LabVIEW via DAQfast and VI-DAQ libraries.

- Scalability:
Up to 16 boards can be installed in a single system, each with a unique board ID (0–Fh).

- Compliance:
Meets VCCI Class A, CE Marking (EMC Directive Class A), and RoHS Directive standards.

### 4. Functionality

Operation Principle:
The PIO-64/64L(PCI)H interfaces digital signals between external devices and a host PC via the PCI bus. Optocouplers isolate the PC system from field signals, ensuring safe and noise-free operation.

Input Function:
Accepts current-sinking outputs from external devices such as sensors, switches, or PLC outputs. The board detects ON/OFF states as digital logic levels.

Output Function:
Drives current-controlled devices such as relays, LEDs, or TTL inputs. Outputs are open-collector type, requiring an external power supply.

Interrupt Function:
16 input channels can generate interrupts. Edge polarity (rising/falling) and enable/disable states are software-configurable.

Digital Filtering:
Software-adjustable filter time constants (0–20 steps) suppress transient noise.
Formula: Filter Time = 2ⁿ / (8 × 10⁶) seconds, where n = 0–20.

Use Cases:
- Industrial automation and process control
- Machine monitoring and data logging
- PLC interfacing and signal conditioning
- Laboratory instrumentation and test systems
- LabVIEW-based data acquisition

Compatibility:
- Windows 7/8/10/11 (32/64-bit)
- Linux kernel-supported distributions
- LabVIEW (via DAQfast and VI-DAQ libraries)
