System Architecture & Signal Flow
Field transmitters (4–20 mA / HART) connect to the module’s screw-terminal or connector front-end. The HESG447398R0020/70EA06A-E performs A/D conversion and transmits digitized process values over the Advant S-bus backplane to the MasterPiece CPU module. Engineering units scaling, alarm limit checking, and signal filtering are configured via ABB’s Control Builder or equivalent Advant engineering tool. The module supports both simplex and redundant I/O configurations depending on rack and controller setup.
