GE Mark V Series Power Supply Board with Drive Controller and LAN Communication for Turbine Control

GE DS215GASCG4AZZ01A(DS200SDCCG4AFD+DS200SLCCG3ACC) Power Supply Board 

Product Description:

The GE DS200SDCCG4AFD is a Drive Controller Board designed for GE’s Mark V Turbine Control System, serving as a core component for managing turbine drive operations. Safety is paramount during its installation and maintenance—strict adherence to installation guidelines is mandatory to avoid electric shock or burn hazards, and users must fully understand these protocols beforehand to protect personnel and ensure system longevity.

As a Mark V Series product, it lacks extensive original online instructional materials, so its product number becomes a key source of hardware details. The “DS200” prefix confirms normal Mark V assembly; other naming chunks indicate a standard PCB coating, three-fold revisions, and membership in Mark V Group 4.

Functionally, it interfaces with other Mark V boards via onboard connectors but does not include factory-installed EPROM chips (users needing EPROMs should opt for similarly named DS215 boards). Its hardware includes jumper switches, TP test points, resistor network arrays, and integrated circuits, with voltage suppression relying on Mark V-standard components (resistors, capacitors, diodes, specialized ICs). For fault handling, it features a RESET button and four reset triggers: manual button press, +5 to +24 V DC input at STBA/NTB/3TB customer interfaces, software-programmed resets, and automatic watchdog system activation. 

The DS200SLCCG3ACC is a LAN (Local Area Network) Communication Board developed by General Electric (GE) specifically for the Mark V Series—GE’s legacy turbine control system line, now obsolete due to manufacturing discontinuation years after its initial release. Despite its obsolescence, the Mark V Series remains significant as one of the final GE Mark product lines to integrate the brand’s patented Speedtronic control technology, which has long been a cornerstone of reliable turbine automation. This board is designed for retrofitting across a broad range of GE drives and exciters, playing a critical role in enabling networked communication for wind, steam, and gas turbine control systems—applications central to the Mark V Series’ functionality.

Its core hardware and functional traits are tailored to streamline LAN integration with host drives: it provides both isolated and non-isolated circuits for drive communication, ensuring signal integrity across different system setups. At its heart is an integrated LAN Control Processor (LCP) that processes all incoming and outgoing LAN signals; the LCP’s program memory is stored in two removable EPROM cartridges, allowing for easy software updates or replacements. To facilitate data exchange between the network and the drive, the board uses dual-ported RAM to enable seamless interfacing between the LCP and the host drive’s Drive Control Processor (DCP).

For user-friendly system management, the DS200SLCCG3ACC supports an attachable alphanumeric programmer keypad, granting access to system diagnostics, configuration settings, and real-time status checks—simplifying maintenance and troubleshooting for technicians. Voltage protection is ensured through a suite of Mark V-standard components, including rectifiers, capacitors, and diodes, while a functional priority-based PCB coating adds an extra layer of durability by safeguarding critical hardware from environmental stress.
