IS200ERDDH1ABB GE Mark VI Speedtronic system
Product Description
The IS200ERDDH1ABB was a major GE PCB element designed to be for the Mark VI turbine management system. The
Mark VI was a vital part of the Speedtronic platform intended to manage heavy gas or steam durable turbines. This
system offered central control of the CCM (Central Control Module) which was connected to the termination boards. The
CCM also connected to an O/I (operator interface) which allowed interfacers to access data regarding the turbines using
dedicated software intended to flawlessly integrate within the system hardware, such as the CIMPLICITY graphics platform.
The IS200ERDDH1ABB was also an element in the third-generation digital excitation platform (EX2100). This control system was
meant to accompany and integrate within MKVI and its HMIs. It worked well within the LS2100 Static Starter. The EX2100 could be
used in tandem with separate retrofitted applications with incorporation finalized through serial or Ethernet Modbus.
The IS200ERDDH1ABB was an IGBT Exciter Regulator/Dynamic Discharge card.
This board had many functions including:
- Controlling the K3 charging station for redundant applications.
- Controlling the K41 de-excitation station, in Simplex applications,
- Providing bridge feedback which helped monitor dc link and output field voltage. This feature also allowed for the
- monitoring of output shunt currents, bridge temperatures, and the IGBT gate drive statuses.
- Providing total gate drive control for field excitation
- Controlling surplus dc-link voltage by way of a dynamic discharge.
The IS200ERDDH1ABB could be used with both redundant and Simplex applications. The board mounts, however, were in
different positions within these different circumstances. The Simplex applications, for example, had the board fastened in the
ERBP backplane. Although, in superfluous applications, dual ERDD boards were often used.
