GE Mark V DS200 Series DS200TCDAH1BHJE Digital I/O Control Board

Product Description

The DS200TCDAH1BHJE is a GE-manufactured digital input/output control board engineered for the Mark V Speedtronic turbine control platform. This board acts as a core interface between field-level discrete signals and the central control processors, supporting deterministic, high-speed signal exchange required in turbine operations.

Designed for long-term operation inside turbine control cabinets, the board emphasizes signal integrity, robust diagnostics, and seamless integration with other Mark V system boards. It is commonly deployed in gas and steam turbine applications where stable and repeatable digital control is mandatory.

Key Functional Overview

The DS200TCDAH1BHJE manages multiple discrete input and output channels used for turbine status monitoring, interlocks, and command execution. It supports rapid state changes and synchronized communication across the Mark V backplane, ensuring coordinated control logic execution during normal operation, startup, and protective events.

Integrated onboard diagnostics allow maintenance engineers to quickly identify signal or board-level issues, reducing troubleshooting time and improving system availability.
