About the IS215WETAH1B
This IS215WETAH1B printed circuit board is a member of General Electric shell company GE Energy's specialized and relatively-new Mark VIe Wind Turbine Control Systems Series, and as such, does not offer a plethora of product-specific original instructional information on the internet. This specific model of printed circuit board also is limited in terms of its general market availability, so even a thorough visual inspection of the product is not available. With that being said, a combination of a IS215WETAH1B individualized part number breakdown with any available instructional information on the product does yield some valuable information. The Mark VIe Wind Turbine Control System Series, as you have probably been able to tell based off of its full extended series name, has a specific set of applications in the control and management systems of popular and compatible wind, gas, and steam turbine automated drive assemblies. The Mark VIe Series' general automated industrial market desirability is additionally well-added-to given the fact that this IS215WETAH1B device's greater Mark VIe Series is one of the final-produced GE Mark product series to make use of the patented Speedtronic control system technology first seen with the Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
For starters, this IS215WETAH1B board is definable as a WETA Top Box A Board Assembly, as designated in original-release factory manual information. Outside of this nugget of information, hardware and performance specifications for the IS215WETAH1B board are only revealed through use of a diligent product number breakdown, beginning with the "IS215" series tag present at the very beginning of this product number. This IS215 series tag has dual naming functionality for the IS215WETAH1B WETA Top Box A Board Assembly; identifying the PCB both as a domestically-manufactured model produced in General Electric's Salem, Virginia factory location, and as a Mark VIe Wind Turbine Series product that is considered to possess a "special" assembly version. While the true reason behind this printed circuit board's specification as a special assembly product is somewhat of a mystery, similar GE Energy PCBs with the IS215 series tag make use of SCOM grounding terminals.
Moving beyond the important IS215 series tag present in the IS215WETAH1B part number, the diligent part number analyzer will notice an inclusion of the WETA functional acronym. This acronym carries the same purpose as any Mark VIe Series functional acronym; to exist as a convenient shorthand for efficient industry-focused or promotional conversation. This WETA acronym is followed in the IS215WETAH1B product number by an inclusion of the "H1" series grouping tag, which, similarly to the aforementioned IS215 series tag, has dual naming functionality for the greater IS215WETAH1B product number. This H1 tag classifies the IS215WETAH1B WETA Top Box A Assembly as a conformally-coated printed circuit board with a group one series grouping. While the true meaning of the Group One Mark VIe Series Grouping has been lost or shrouded in relative obscurity, the conformal coating style specific to this product has been well-studied. Conformal printed circuit board coating, unlike the alternative normal style of printed circuit board coating; is an exhaustively-layered, thin, chemically-applied level of protective insulatory coating that should envelop every surface of every component affixed to the base board of this IS215WETAH1B model. The final trailing "B" digit in the IS215WETAH1B product number reveals this part's singular functional revision, graded at a "B" rating. This functional revision, as indicated by its name, makes major improvements to the overall functionality and performance specifications of this IS215WETAH1B product, without sacrificing for durability or aesthetic choice purposes. This product is available for both repair and replacement here at AX Control, with a standard one to two week lead time on repairs.
