IS200WREAH1A General Electric AERO TRIP TB DBRD

Overview

The IS200WREAH1A is a terminal board used in GE’s Mark VIe Speedtronic turbine control platform for aeroderivative turbines. It functions as

an Aero Trip Terminal Board (DBRD)—a hardware interface that collects and routes critical trip signals, inputs, and outputs associated

 with turbine emergency protection functions. These terminal boards interface with the Mark VIe I/O packs and optional daughter

 / accessory boards to execute fast and reliable turbine trip logic when abnormal or unsafe conditions occur.The

“WREAH1A” suffix typically denotes specific configurations or revisions of the board within the Mark

VIe family that align with TMR (Triple Modular Redundancy)

or simplex system setups.

FAQ about 0552N1QLG132A-06 V1.1 

In what system is the IS200WREAH1A used?

A: It is used with General Electric Mark VIe (Speedtronic) turbine control systems for gas turbines and aeroderivative applications.

What signals does this board handle?

A: It typically handles trip contact inputs, emergency stop conditions, and routing of those signals into the turbine

protection logic. It pairs with other boards / I/O packs for full speed sensing and trip actuation functions.

Does this board operate alone?

A: No — it’s part of a suite of GE Mark VIe terminal boards and I/O packs. The full emergency

 trip logic usually includes I/O modules (e.g., PPRA/PPRAS), other terminal

boards (e.g., TREA/TREAS), and option cards.
