Working Principle
The PFSA140 first converts incoming AC power to stable DC power through an internal switching power supply circuit, which is then regulated and protected by overvoltage/overcurrent circuits. For signal processing, analog signals from sensors (e.g., 4–20mA) are amplified and filtered before being converted to digital signals by an ADC for microprocessor processing. The microprocessor executes pre-programmed logic to control output signals (e.g., driving relays or adjusting analog outputs) and communicates with the upper-level system via the RS485 interface. The modular design ensures that each functional unit (power supply, signal conditioning, communication) operates independently, with isolation technology preventing interference between circuits to maintain system stability.
