Function and Working Principle
The F3WD64-3F combines digital input monitoring and digital output control within one module.
The input section continuously detects ON/OFF signals from field devices such as push buttons, proximity sensors, photoelectric sensors, and limit switches. These signals are processed by the PLC CPU according to the user program. The CPU then sends commands to the output section, which controls external devices including relays, contactors, solenoid valves, and indicator lamps.
The integrated design improves wiring efficiency while reducing installation costs and cabinet space.
Operating Sequence
- Receive digital signals from field devices.
- Transfer input status to the PLC CPU.
- Execute the user control program.
- Generate output commands.
- Drive external devices through transistor outputs.
- Repeat the control cycle continuously.
