Product Description

The IS215WEPAH2B printed circuit board exists as a Wind Energy Pitch Axis important to General Electric shell company GE Energy's Mark VIe Speedtronic Series line of wind turbine control system automated drives and drive component parts. This product's status as a Wind Energy Pitch Axis is observable solely from a breakdown of its unique product part functional acronym; which itself is embedded in the IS215WEPAH2B individualized product part number. This Wind Energy Pitch Axis is considered a modified version of the original IS215WEPAH2B product; featuring a singular functional revision graded at a "B" rating. This functional revision is considered functional as it promotes an enhance overall functionality and efficiency for the IS215WEPAH2B Pitch Axis, while not focused on the aesthetics or dimensions of the product. 

Hardware Tips and Specifications

As with any similar style of GE Energy Mark VIe series printed circuit board; the IS215WEPAH2B features a large number of unique hardware components that contribute to its intended functionality as a Wind Energy Pitch Axis. One component crucial to maintaining this functionality is the IS215WEPAH2B board's input and output types, off which it has several. The I/O types present on the base board of this WEPA-abbreviated Wind Energy Pitch Axis include:

  • 8 total analog inputs
  • 1 incremental encoder input
  • One separate analog input
  • 20 total discrete inputs
  • 2 total discrete outputs
  • 9 relay outputs
  • 2 RS-485 interfaces
  • 2 pulse-width modulated control outputs

While the input and output styles present with this IS215 WEPA model's assembly are certainly important, they are in no way the only relevant pieces of hardware. In fact, the IS215 tag present at the very beginning of the IS215WEPAH2B part number asserts this product's status as a printed circuit board with a special assembly style. In specific, the IS215WEPAH2B can be defined as a special modular assembly made up of AEPAH1B and the BPPB attached daughterboard. A lot of other information pertinent to this Wind Energy Pitch Axis is derivable from a simple inspection of its individualized product part number. The aforementioned IS215 series tag has dual naming responsibility for the WEPA assembly; additionally designating this product a U.S.-made model manufactured in General Electric's Salem, Virginia location. The "H2B" portion of the IS215WEPAH2B product part number has three-way naming responsibilities; designating this PCB as a once-revised, conformally-coated PCB with a group 2 Mark VIe series grouping. For a more thorough explanation of the IS215WEPAH2B descriptive product part number, a diagrammed IS215WEPAH2B Part Number Breakdown is available above, through our "manuals" tab.

Frequently Asked Questions about IS215WEPAH2B

Is this PCB's WEPA acronym accurate to its functional description?

Yes. While many of the functional acronyms featured on our product pages here at AX Control are not literal translations of their functional descriptions, the WEPA acronym stands for the correct functional description of Wind Energy Pitch Axis.

Why is this IS215WEPAH2B model PCB considered to have a special assembly type?

This IS215WEPAH2B model's IS215 tag suggest that incorporates a SCOM grounding line and correspondent SCOM screws, which elevates this model to a special assembly designation.

What is conformal PCB coating?

Conformal PCB coating, as present on the base board of the IS215WEPAH2B, is a thin layer of chemically-appied printed circuit board protective coating that should extend exhaustively over every surface of every component available on the board.

Reviews For IS215WEPAH2B

Internal Review

Developed exclusively for GE Energy's Mark VIe Series of wind turbine system controls, the IS215WEPAH2B Wind Energy Pitch Axis is a special modular assembly that includes the previously-existing Mark VIe AEPAH1B printed circuit board and the BPPB attached component daughterboard. All of the hardware components in this special assembly should be well-protected beneath a conformally-coated PCB layer. Before making a purchase decision for this product, it is important to understand it is a revised version of the original IS215WEPAH2 product, and that all of the hardware specifications and dimensions outlined in original factory-issued manuals may be inaccurate. - AX Control Lead Technician
