Function and Working Principle
The 140DAI54000 is used to detect ON/OFF state signals from field devices such as:
- Push buttons
- Limit switches
- Proximity sensors (AC type)
- Relay contacts
Working Principle
- Field device applies 115 V AC signal
- Input channel detects voltage presence
- Signal is filtered and isolated internally
- PLC reads status as logic 1 (ON) or 0 (OFF)
Signal Flow
Field Device → Input Terminal → Isolation Circuit → PLC Backplane → Control Logic
