The DS200KLDBG1A is a human-interface and mixed-I/O board used inside GE EX2000 and Mark V Speedtronic drive or excitation cubicles. Occupying a double-slot position, it combines three functions in one unit:
-
Graphical LCD display – 240×64 pixel monochrome screen for real-time data, alarms, and menu navigation.
-
Keypad with LEDs – tactile keys and 16-segment LED indicators that let operators browse menus, adjust set-points, or acknowledge faults without a laptop.
-
Local I/O hub – 24 digital inputs (dry contacts or 24 VDC) plus 12 Form-C relay outputs (3 A @ 125 VDC) for local push-buttons, indicator lamps, or lock-out valves.
Power is dual-supply: +5 V @ 6 A from the VME backplane for logic/LCD, and 18–32 VDC field power for relays and keypad backlight. All medium-voltage connections are made through keyed front-panel headers, keeping 125 VDC trip circuits away from the 5 V logic side.
Because the card is conformal-coated and rated 40–70 °C, it survives the heat and humidity common in turbine compartments without additional HVAC.

Core Features & Customer Value
Built-in operator interface – Eliminates the need for an external panel PC or HMI, cutting hardware cost and cabinet depth in excitation or compressor-drive skids

.
24 + 12 local I/O – Dedicated push-buttons, lamps, and lock-out valves can be wired directly to the card, reducing marshalling and external relay count
.
Graphical LCD + keypad – Real-time bar graphs, trend screens, and alarm logs let operators diagnose issues on the spot without a laptop, shortening mean-time-to-repair
.
Dual-supply design – 5 V logic and 28 V field power are segregated; relay coils can be powered from the same 24 V battery that feeds contactors, simplifying power distribution
.
Zone-2 / marine certified – Conformal-coated PCB is certified for Class I Div. 2 and offshore environments, allowing direct installation in hazardous-location turbine skids without additional purge systems
.
Typical Applications
In combined-cycle power plants the DS200KLDBG1A is installed in the local control panel of EX2000 excitation cubicles. Operators use the keypad to view generator field current, adjust voltage set-points, or acknowledge alarms without opening the laptop

.
In pipeline compressor stations the same card drives 24 V lock-out valves and reads auxiliary contact status, giving local start/stop capability when the remote SCADA link is down
.
Because the module is certified for marine environments, it is also used on off-shore platforms for engine-driven generators where a fan-less, Zone-2 operator interface is mandatory
