Working Principle:
Metso D201126 receives binary (discrete) signals from field devices representing equipment open/closed status, limit switch positions, push button states, or sensor binary outputs. The module converts these physical signals into digital formats understandable by PLC or DCS systems for logical processing, status monitoring, alarm management, and automation control. The module provides the control system with real-time process status information enabling precise monitoring and control of industrial machinery and processes.
