Functional Revision 1 A

Product Description

The IS200WEMAH1A is a Mark VIe Series component manufactured by GE; more specifically by General Electric shell company GE Energy. The Mark VIe was one of the last gas/steam turbine management systems created and released under the Speedtronic name, and in this instance, provides control system options for a range of compatible Gas, Steam, and Wind Turbines. This particular IS200WEMAH1A Mark VIe Series printed circuit board was designed intended to be used in wind turbine control applications specifically, and carries a singular functional revision rated at an "A" grade. This A-rated revision is a functional revision as it makes improvements to the overall functionality of the IS200WEMAH1A board, without sacrificing for durability or aesthetic purposes. The singular functional revision present on the IS200WEMAH1A board modifies it from the original IS200WEMAH1A parent board, as mentioned above.

Hardware Tips and Specifications

The IS200WEMAH1A is a relatively large, component-dense board. The board has one large and one small transformer. The center of the board is designed to accept an auxiliary board and has four standoffs mounted to the board to support this board if or when it is installed. Two vertical plugs are located near these standoffs for power/communications for the daughterboard. On the opposite side of the auxiliary board location, there exists a line of resistors marked “Estop” and DIN01 through DIN33. The WEMA-abbreviated IS200WEMAH1A board makes use of 27 total digital inputs, 2 analog thermistor temperature sensor inputs, 9 relay contact outputs, and 3 separate solid-state relay outputs.

The IS200WEMAH1A;s board assembly includes four terminal strips. These terminal strip components are located side-by-side along one board edge, and are paired with fifteen total relays/contactors. The board has nine heat sink components, most of which are located next to their corresponding relay components. Other components obvious on the base board of the IS200WEMAH1A include six fuses, one switch component, several high voltage electrolytic capacitors as well as other capacitors, terminal contacts, and resistors, including metal film and CCR resistors. The three different fuse types included in the IS200WEMAH1A board assembly are:

  • LITTELFUSE 218.315, 218.315H,218.315HXP
  • COOPER BUSSMANN BK/S506-1-RLITTELFUSE 218001, 218001MXP,218001P

In terms of connector types, this WEMA-abbreviated board has two vertical pin header connectors, three black plugs (P2, P5, and J7) and 18 white plugs that vary from 2-position plugs to 18-position plugs. As indicated in the IS200 series tag present in the IS200WEMAH1A board's individualized product number, this model PCB does not make use of any special assembly type, although it is important to note that its singular functional revision may alter the factory-defined performance specifications or dimensions of the PCB.

Frequently Asked Questions about IS200WEMAH1A

Is the Mark VIe Wind Series an actual series?

No. While the Mark VIe Wind Series is not an actual series of its own, the hardware and performance differences between the Mark VIe Wind Turbine-applicable models and the Mark VIe steam and gas models is extreme enough to warrant its placement in a separate series, for your convenience.

How was this product's singular functional revision indicated in the IS200WEMAH1A product number?

The IS200WEMAH1A PCB's singular A-rated functional revision is indicated through the presence of the trailing "A" digit in the individualized IS200WEMAH1A product number.

What does the IS200WEMAH1A PCB's conformal printed circuit board coating involve?

The conformal-style PCB coating present on this IS200WEMAH1A model is a thin, chemically-applied layer of PCB protective coating that should envelop every surface or extension of every hardware component affixed to the IS200WEMAH1A base circuit board.

Reviews For IS200WEMAH1A

Internal Review

This IS200WEMAH1A printed circuit board has a relatively small amount of original, factory-issued instructional manual materials available online for customer or reseller research purposes, which led to its rather muted and basic description as a "Wind Printed Circuit Board." It is entirely necessary, however, to make an inclusion of the "Wind" description, as Mark VIe wind turbine-oriented printed circuit boards and Mark VIe gas or steam turbine-oriented PCBs are known to have several crucial differences in their hardware component makeups. - AX Control Lead Technician
