### 2. Key Features

- High-Speed Opto-Isolated I/O:
32 opto-isolated input channels and 32 opto-isolated open-collector output channels with a response time of ≤ 5 µs.

- Electrical Isolation:
Complete isolation between the PCI bus and I/O interface via high-speed opto-couplers, ensuring superior noise immunity and protection against ground loops.

- Flexible Power Configuration:
Inputs and outputs are grouped in sets of 16 channels, each group supporting independent external power supplies (12–24 V DC ± 10%).

- Interrupt Capability:
All 32 input channels can be configured as interrupt sources. The interrupt trigger edge (rising or falling) is selectable per channel.

- Digital Filtering:
Built-in digital filter prevents false triggering due to noise or contact chattering. Filter time configurable via software (0–20 steps, 2ⁿ / (8 × 10⁶) s).

- Output Protection:
Each output transistor includes surge voltage and overcurrent protection. Polyswitch resettable fuses protect every eight output lines.

- Compatibility:
Connector shape and signal arrangement are fully compatible with the earlier PIO-32/32F(PCI) model.

- Software Support:
Includes Windows and Linux driver libraries (API-PAC(W32)), LabVIEW VI-DAQ library, and sample programs for Visual Basic, Visual C/C++, and gcc.

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