Product Role & System Fit
For industrial automation systems — especially in power generation and heavy-duty turbine control — discrete analogue signals from power modules and SCR bridges must be translated into a form that digital logic controllers can reliably interpret. The GE DS200SHVMG1AFE fulfils this exact function within General Electric’s Mark V DS200 series of control modules. It is a SCR High Voltage M-Frame Interface Board engineered to provide high-integrity signal conversion and routing between the high-voltage SCR bridge, power supply boards like the DCFB or SDCI, and power connect cards (PCCA).
Because GE Mark V systems evolved over decades and were deployed in varied industrial environments — from steam and gas turbines to large exciters — the interface board acts as a linchpin ensuring that the raw analogue voltage and current information can be digitised and processed by the controller logic. In Mark V racks, this board typically fits into a dedicated backplane slot and is part of the broader SCR drive control section. Its presence ensures that critical power conversion and gate drive signals are presented to the control system in a deterministic and conditioned form, which is essential for safety logic, protective interlocks, and precise control of turbine operations.
Unlike general-purpose PLC modules, the GE DS200SHVMG1AFE does not execute user logic; it performs hardware-level interface and conditioning tasks that ensure SCR power stages communicate cleanly with downstream digital processing modules. In retrofit and legacy system support scenarios, technicians value this board because it preserves system architecture — meaning there is no need to redesign existing logic or rethink rack layouts to accommodate newer digital converters.
