YOKOGAWA SAT145 Series Technical Notes

The Evolution of SAT145 Architecture

The SAT145 series was introduced as part of YOKOGAWA's CENTUM CS platform in the mid-1990s, designed to replace discrete signal conditioning hardware with integrated, bus-coupled I/O modules. Early variants supported basic thermocouple types (K, J, T) with 8-channel density. As the CENTUM CS3000 platform matured through the 2000s, the SAT145 line expanded to include multi-range RTD inputs, higher channel counts, and enhanced noise rejection for electrically harsh environments.

Sourcing Hard-to-Find & Obsolete SAT145 Parts

Q: How is condition confirmed before quotation?
A: Available condition, photos, test records and documentation are checked according to the requested model and sourcing channel before a formal RFQ response.

Quality Control for the SAT145 Range

The SAT145 series employs a proprietary YOKOGAWA backplane bus protocol for communication with the FCS processor. Standard bench testing is insufficient to validate module integrity; DriveKNMS utilizes a CENTUM CS3000 live test rack environment to perform end-to-end functional verification of each SAT145 unit prior to shipment.
