Function and Working Principle
The F3XD16-3F continuously monitors digital DC input signals from connected field devices and transfers their ON/OFF status to the FA-M3 CPU.
Each input channel is electrically isolated using photocouplers, protecting the PLC from electrical noise and voltage disturbances. During every PLC scan cycle, the CPU reads the input status, executes the user program, and updates system outputs accordingly. Adjustable input filtering helps eliminate signal noise while supporting high-speed response when required.
Operating Sequence
- Receive DC signals from field devices.
- Detect input status changes.
- Convert electrical signals into digital PLC data.
- Transfer input information to the CPU.
- Execute the user control program.
- Repeat the scan cycle continuously.
