Function and Working Principle
The F3XD32-3F continuously monitors digital DC input signals from field devices and transfers their ON/OFF status to the FA-M3 CPU.
Each input channel is isolated by photocouplers to improve immunity to electrical noise and ensure stable operation in industrial environments. During each PLC scan cycle, the CPU reads the input status, executes the control program, and updates the control system accordingly. Configurable sampling times and interrupt functions allow rapid detection of critical input events.
Operating Sequence
- Receive digital signals from field devices.
- Detect ON/OFF status changes.
- Convert electrical signals into digital input data.
- Transfer input information to the PLC CPU.
- Execute the user control program.
- Repeat the scan cycle continuously.
