GE DS200KLDBG1ABC DS215KLDBG1AZZ03A Display Keypad Board

The GE DS200KLDBG1ABC together with assembly number DS215KLDBG1AZZ03A is a display‑keypad driver board for Speedtronic Mark V turbine control systems. It serves as the man‑machine interface gateway between the main turbine controller and cabinet‑door operator panel, driving VFD/LED display and processing keypad input commands from site operators.

This rack‑mount PCB carries display driving logic, jumper configuration points and multi‑pin internal connectors. It transmits real‑time turbine parameters, alarm messages and accepts operator set‑point adjustments. It is a key aftermarket spare for overhaul, maintenance and retrofitting of gas‑steam turbine control cabinets in power‑plant facilities.
