About IS200WEMAH1AEA

The IS200WEMAH1AEA is a General Electric printed circuit board assembly that is part of the company’s Mark VI turbine control system. The system is one of the final gas and steam turbine control architectures released by General Electric under the “Speedtronic” banner, specifically designed to provide reliable and flexible industrial turbine management. This is the third Speedtronic system to offer users the option of TMR or Triple Modular Redundancy. However, the Mark VI also offers a Simplex system option for smaller or less complex systems that cannot benefit from the TMR system.

Hardware Tips and Specifications

The IS200WEMAH1AEA is a fairly large and component-dense circuit board. It has a built-in standoff located in the center of the board. This is to allow the user to install auxiliary boards at a later date as per the convenience of the owner. In addition to the unique bracket that will benefit IS200WEMAH1AEA owners, the PCB features a number of components worth noting, including but not limited to:

At least four fuses

Multiple relays, each with a different label describing the relay function

Over five hundred individual resistors for current and voltage management

At least ten plugs and fuses for compatibility

A range of transistors

Four terminal blocks, labeled TB1 through TB4

Two different types of transformers, labeled T1 and T2

Nine heat sinks

Vertical pin connectors

Most of the components on the IS200WEMAH1AEA are surface mount, but some, like some resistors, are still through-hole mounted. Most components are marked with some kind of reference mark to aid identification.

The IS200WEMAH1AEA board is factory drilled in multiple locations, including the board corners and within the body of the board. These drilled holes are surrounded by conductive material for optimal mounting.
