Operation Principle:
- External digital signals (0–24 V DC) are applied to the input terminals.
- Each input passes through an opto-isolator, converting the electrical signal into an optical signal for galvanic isolation.
- The optical signal is then converted back to a logic-level signal readable by the PCI controller.
- The card continuously monitors all channels and can generate interrupts when a change of state (COS) occurs on any input line.
Use Cases and Applications:
- Industrial automation and process control
- Machine status monitoring
- Event counting and digital signal logging
- Safety interlock and alarm systems
