The Yokogawa AAV142-S50 is a high-density analog input module used in Yokogawa CENTUM VP / CENTUM CS 3000 distributed control systems (DCS).
It is designed to collect industrial field analog voltage signals (typically -10 V to +10 V DC or standardized process signals) and convert them into digital data for process control, monitoring, and automation logic. The module is widely used in chemical plants, power generation, oil & gas, and large-scale industrial process systems where stable and precise data acquisition is required.
This module belongs to Yokogawa’s AAV series analog input family, known for stability, diagnostic capability, and integration with redundant DCS architectures.
