Yokogawa S9649FA | Cable Adapter / Connection Board

Product Overview

The Yokogawa S9649FA is a specialized cable adapter or connection board used in the Yokogawa CENTUM VP and CENTUM CS 3000 Distributed Control Systems (DCS). This component acts as a crucial bridge between Analog Input (AI) / Analog Output (AO) modules and field wiring or external signal conditioners. It simplifies the connection and distribution of high-density I/O signals (commonly 16-channel or 32-channel modules) in environments where space is limited, such as industrial cabinets and control rooms.

The S96xx series is typically associated with terminal boards or adapters in Yokogawa systems, where the focus is on providing high-density connections that are both efficient and easy to maintain. The FA suffix generally indicates a "Field Application" design, which often includes built-in precision resistors for current-to-voltage conversion (e.g., converting a 4-20 mA signal to a 1-5 V signal).
