Function and Working Principle
The F3WD64-3P performs both digital signal acquisition and output control within a single module.
The input section continuously monitors field devices such as push buttons, proximity sensors, photoelectric sensors, and limit switches. Input signals are transmitted to the PLC CPU, where the user program determines the required control logic. The CPU then activates the output channels, allowing the module to control external equipment such as relays, solenoid valves, indicator lamps, and contactors.
The integrated design improves system efficiency while reducing hardware requirements and installation complexity.
Operating Sequence
- Receive digital input signals from field devices.
- Transfer input data to the PLC CPU.
- Execute the control program.
- Generate digital output commands.
- Drive external actuators through transistor outputs.
- Repeat the control cycle continuously.
