4. Functionality
The PIO-16/16T(PC)H functions as a high-speed digital interface between a PC and external TTL-level devices. It allows direct reading of digital input signals and control of digital outputs through software commands or interrupt-driven routines.
- Input Function: Each of the 16 input channels accepts TTL-level signals (0–5VDC). Negative logic is used, meaning a logical “0” corresponds to a high voltage level.
- Output Function: The 16 output channels are open collector type, capable of sinking up to 40mA per channel at 30VDC. These outputs can drive LEDs, relays (through external drivers), or other TTL-compatible loads.
- Interrupt Handling: The board can generate interrupts based on input signal changes, allowing real-time event detection. Two interrupt lines can be assigned from IRQ 3–7 or 9.
- Use Cases:
- Industrial automation and process control
- Machine status monitoring
- Digital signal acquisition and control in laboratory systems
- TTL-level device interfacing (sensors, switches, logic circuits)
- Embedded control and test benches
- Compatibility: Works with standard PC/AT bus systems and supports integration with CONTEC’s software libraries for Windows, Linux, and LabVIEW.
