### 4. Functionality
The PIO-16/16L(PC)V functions as a digital interface between a PC/AT system and external industrial devices.
- Input Function:
Each of the 16 input channels receives 12–24 VDC signals from sensors, switches, or other control devices. The opto-couplers isolate these signals from the PC’s internal circuitry, converting them into logic-level signals for software processing.
- Output Function:
The 16 open-collector output channels can drive external loads such as relays, solenoids, or indicator lamps. Each output transistor can sink up to 200 mA at 35 VDC.
- Interrupt Handling:
The board can generate hardware interrupts on specified input transitions (falling edge). Two interrupt lines can be assigned from available IRQs, allowing real-time event detection.
- Negative Logic Operation:
The input channels share a positive common terminal, meaning a low-level (0 V) signal represents an ON state. This configuration is widely used in industrial control systems.
- Applications:
- Factory automation and process control
- Machine status monitoring
- PLC signal interfacing
- Data acquisition and event logging
