System Architecture & Signal Flow
The SAT145-S65 mounts directly into the CENTUM VP or CS 3000 I/O unit (IOU) rack. Field thermocouple and RTD wiring terminates at the module’s front-face terminal block or marshalling cabinet via the associated terminal board. The module performs on-board cold junction compensation (CJC) for thermocouple inputs and 3-wire/4-wire RTD linearization, converting raw sensor signals to engineering-unit values transmitted over the internal DCS bus to the Field Control Station (FCS). The FCS then executes control logic and communicates with the Human Interface Station (HIS) via the Vnet/IP control network.
Typical Signal Path: Field Sensor → SAT145-S65 Terminal Block → A/D Conversion & CJC → DCS Bus → FCS Control Logic → HIS / SCADA
