4. Working Principle & Signal Flow

1. Equipment Mounting & Power Supply: Install the WOODWARD 5601-1126 current-to-pressure converter at the designated position (inside control cabinet or on-site equipment), connect the matched power supply, wire the current input source to signal terminals, and connect output and communication interfaces according to site requirements to complete deployment.
2. Signal Input & Acquisition: Input current signal (standard 4~20mA) is transmitted to the core conversion area through input terminals. The converter collects real-time current signals and monitors signal stability via built-in detection circuits.
3. Signal Conversion & Processing: The internal conversion chip amplifies and filters the collected current signals to eliminate high-frequency noise. It then adopts proportional conversion algorithm to accurately convert current signals into corresponding output pressure, maintaining linear input-output relation, and switches output type among voltage, current or frequency as required.
4. Output & Protection: Converted pressure signals and corresponding output signals are transmitted to actuators or control systems to support equipment pressure regulation. Meanwhile, the converter monitors its operating status and signal conversion process in real time. Once abnormal signals or pressure deviations are detected, the built-in protection mechanism activates immediately to cut off abnormal output and trigger alarm indication, preventing equipment damage and fault escalation.
5. Data Transmission & Monitoring: Through the communication interface, the converter transmits real-time conversion data, operating status and alarm information to DCS/PLC systems. Operators can remotely monitor the conversion process, trace historical data and adjust parameters, improving operation and maintenance efficiency.
