The IS200WREAH1A is an industrial control system spare part manufactured by General Electric, primarily used in Mark VI / Mark VIe gas turbine and steam turbine control systems.
Seamless TMR 2oo3 Voting Integration
Robust Galvanic Isolation & Active Diagnostics
4-Channel High-Reliability Dry Contact Inputs
The GE Industrial Steam Turbine Control (ISTC) is part of the Mark VI turbine controls. The ISTC provides basic control functions. These functions can then be expanded in small increments for various levels of control, protection, and monitoring for the turbine, the auxiliary systems, and the driven load equipment (generator / compressor / pump). The control module consists of a processor board, communication board, and I/O boards mounted in a single 21-slot (VME type) rack. I/O boards are connected to individual terminal boards by computer-type cables with 37-pin, D-type connectors. The terminal boards have pluggable, barrier-type terminal blocks. I/O and terminal boards can be arranged in various combinations and added in the field for future expansion.

Thermal Power
Captures emergency shutdown signals from manual mushroom e-stop buttons, low bearing oil pressure switches, and condenser low vacuum trip switches, converting them into isolated inputs for the master trip circuit.
Gas Power
Monitors critical fire-and-gas detection contacts, enclosure ventilation failure switches, and fuel gas high/low pressure switches to trigger immediate fuel isolation via the trip board.
Nuclear Power
Routes safety-critical dry contact inputs from the reactor protection system into the TMR 2oo3 voting network, eliminating the risk of a false turbine trip that could destabilize the electrical grid.
Petrochemical
Collects critical mechanical interlock data (such as severe casing vibration or seal oil failure) to execute an instantaneous safety trip before volatile hydrocarbons leak or ignite.
Oil & Gas
Serves as the localized emergency shutoff interface in remote pipeline stations, collecting manual ESD station signals and line break valve status signals to execute emergency runtime stops.
To ensure system safety and prevent component damage, never attempt to install or hot-swap the IS200WREAH1A daughterboard while the turbine is online, as it directly handles active emergency shutdown loops. When stacking it onto the primary trip terminal board (such as the IS200TREAH1A), verify strict hardware pin alignment to preserve the integrity of the 2oo3 voting logic. Always maintain field wiring loops clean and dry to prevent impedance drops across its 24V DC dry contact inputs, and ensure the control cabinet is properly grounded to eliminate moisture-induced electrical loops in harsh industrial environments.
The IS200WREAH1A is an Aero Trip Terminal Board developed by General Electric (GE).
How do you use the IS200WREAH1A terminal board?
The IS200WREAH1A is used as an expansion or plug-in daughterboard. It mounts directly onto a primary turbine trip terminal board (such as the TREA board) to add 4 extra channels of dry contact inputs for emergency machine tripping.
What type of input signals does the IS200WREAH1A accept?
The board is equipped to handle 4 discrete channels of 24V DC dry contact inputs. These are mechanical or electronic switch contacts provided by external safety devices.
In what type of machinery is the IS200WREAH1A typically installed?
It is primarily installed in heavy-duty rotating machinery control cabinets, most notably in GE industrial gas turbines, steam turbines, and aero-derivative turbine generators.
Does the IS200WREAH1A support redundant voting configurations?
Yes. The inputs from the IS200WREAH1A can be routed into the Mark VI/VIe system's Triple Modular Redundant (TMR) architecture, allowing the system to run 2-out-of-3 (2oo3) voting logic for safety-critical trip commands.
