### 4. Functionality
The PI‑64L(PC) functions as a digital input interface between field devices and a PC‑based control or monitoring system. Each input channel detects the ON/OFF state of external DC signals (12–24 V DC) and transfers the logic state to the host computer through the ISA bus.
Working Principle:
- External DC signals are applied to the input terminals.
- Each input passes through a current‑limiting resistor and drives an opto‑coupler.
- The opto‑coupler converts the electrical signal into an optical signal, isolating the external circuit from the PC logic.
- The optical signal is reconverted to a logic‑level signal within the board and read by the host system.
Typical Applications:
- Monitoring of limit switches, proximity sensors, and photoelectric sensors.
- Status acquisition from relays, contactors, and PLC outputs.
- Industrial process monitoring and alarm systems.
- Machine control and safety interlock systems.
