The Yokogawa ADV142-S03 S1 is a high-voltage AC digital input module designed specifically for CENTUM VP systems, featuring 16 input channels. It is primarily used to receive 200V to 240V AC field device signals, such as operating feedback from high-voltage motors, auxiliary contact status of circuit breakers, or switching signals from various industrial power distribution systems.
This module offers extremely high industrial reliability, supporting dual redundancy configurations to ensure continuous monitoring of field conditions by the control system even if a single module fails. It employs advanced digital filtering algorithms to effectively filter out induced voltage or contact jitter caused by long-distance cable transmission in industrial environments, providing the controller with accurate and clean logic signals.
The ADV142-S03 S1 YOKOGAWA Digital Input Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Compared to the S02 version, the S03 version typically features fine-tuning in specific terminal connection methods or external noise filtering characteristics to meet specific industry standards or cable compatibility requirements.
The ADV142-S03 S1 detects the AC voltage on the field side through its input interface. When the external contacts close, approximately 220V AC current flows into the module. The internal circuitry first performs current limiting, rectification, and filtering, and then drives the optocoupler to generate internal logic levels. This optical conversion mechanism achieves complete isolation between the physical circuitry and the system's digital circuitry. Finally, the module's microprocessor scans the optocoupler output status of each channel, encapsulates it into digital data, and sends it to the field control unit (FCU) via the system bus.
