### 4. Functionality
The PIO‑32/32T(PC) functions as a high‑speed digital interface between a PC and external TTL‑compatible devices. It provides direct access to 32 input and 32 output lines through a 96‑pin half‑pitch connector. Each input channel detects TTL‑level logic states, while each output channel can drive external loads via open‑collector transistors.
Operation Principle:
- Inputs: Each input line is pulled up internally to +5 V through a 10 kΩ resistor. When an external device drives the line low (0 V), the input is recognized as logic “1” (ON).
- Outputs: Open‑collector outputs can sink current from external circuits up to 40 mA per channel. External pull‑up resistors or loads can be connected to +5 V or higher voltages (up to 30 VDC).
- Interrupts: The board can generate hardware interrupts based on input signal transitions. The interrupt trigger edge (rising or falling) and digital filter time constants are configurable via software.
- Digital Filtering: The digital filter suppresses transient noise and contact bounce, ensuring stable signal detection in noisy environments.
Typical Applications:
- Industrial automation and machine control
- Data acquisition and monitoring systems
- Production line control and inspection equipment
- Laboratory instrumentation and test benches
- Logic signal monitoring and pattern generation
- Interface for PLCs, sensors, and actuators
Compatibility:
- Compatible with CONTEC’s PIO‑32/32T(PC)H and PCI‑based PIO‑32/32T(PCI) models.
