Hardware Tips and Specifications

This IS215AEPAH1A Alternative Energy Power Assembly may be best understood when its hardware elements are contextualized according to the intended function of this printed circuit board.

The first descriptor for the function of this AEPA-abbreviated product is present in its functional description as an alternative energy power supply assembly.

This functional description happens to be an exact match to the AEPA functional acronym for this product, a rare blessing for a specialized Mark VIe series product.

The series to which this IS215AEPAH1A board belongs actually provides additional insight into the functionality of this product.

Considering the place of the IS215AEPAH1A PCB in the Mark VIe family of wind turbine control systems, it is not surprising that this GE Energy board is dedicated to wind turbine applications.

Now that the functional status of this IS215AEPAH1A PCB as an alternative energy power supply assembly has been described.

Then it is possible to highlight some of the hardware specifications available for this Mark VIe wind turbine series product.

Considering this product’s place in the specialized and recently developed Mark VIe wind turbine family, little original product-specific instruction manual material detailing the hardware of this IS215AEPAH1A PCB exists online.

That said, this initial Mark VIe series label identifies the board as an alternative energy power supply assembly with special component versions.

This IS215 series label has dual naming capabilities for this IS215AEPAH1A product; it also outlines its status as a domestic GE printed circuit board.

The original manufacturing location of this PCB can be traced more specifically to GE’s plant location in Salem, Virginia.

In this IS215AEPAH1A part number, the IS215 series label is followed by an example of the AEPA functional acronym.

It is itself followed by the H1 series grouping label, which, like the IS215 series label mentioned earlier, provides a dual naming convention for this product.

This H1 grouping label indicates that the product is a conformal coated printed circuit board with Mark VIe series grouping.

While the conformal style of PCB coating specific to this power supply assembly is well documented, given its widespread use on General Electric circuit boards, the first Mark VIe grouping of this part is the Mark VIe grouping.

Features

A distinctive feature of the VCMI is that it acts exclusively as a VMEbus master within the control and input/output racks.

The VCMI is responsible for the VMEbus, a standardized computer bus structure, and oversees the coordination of data transfer and control signals within these racks.

The VCMI manages the assignment of unique identification (ID) to all boards in the rack and their associated terminal boards.

This ID management function ensures that the various components within the rack are identified and interacted with in a systematic and organized manner, thereby increasing the overall efficiency and reliability of the system.

The VCMI Bus Master Controller is a multifaceted communications hub that seamlessly connects controllers, I/O boards and the broader system control network.

As a VME Bus Master Controller in a given rack, it enhances its ability to manage and optimize the flow of information, ultimately improving the performance and cohesiveness of the integrated system.

Board Type: 6U High VME Boards

The boards specified are classified as 6U High VME boards and are dimensioned to meet the widely adopted VME standard. At 6U high, the boards conform to a standard form factor and are compatible with a range of systems and platforms that meet the same specifications.

At 0.787 inches wide, this VME board integrates seamlessly into the VME chassis, contributing to the modularity and scalability of the overall system.

Processors

Texas Instruments TMS320C32 32-bit Digital Signal Processor: At the heart of this VME board is the highly capable Texas Instruments TMS320C32.

This processor is a 32-bit digital signal processor (DSP) known for its ability to handle complex mathematical calculations and signal processing tasks.

The TMS320C32 is a rugged, purpose-built processor ideally suited for applications requiring high-speed, efficient digital signal processing, and is therefore well suited to the intended function of this board.

The program assists in managing system setup and automatically flags programming errors or conflicts as the user adjusts setpoints.

The 745-W2-P1-G1-HI-T-H’s enhanced 40-character display is larger than the base model and includes an extended keypad for easy manual setpoint entry.

The enclosure is 9″ high by 7″ wide by 7 ⅛” deep. The transformer protection system can be mounted on a standard 19″ panel, but care should be taken that the enclosure door opens and closes freely without contact with other components.

A number of LEDs on the front of the chassis alert the user to various statuses and errors in real time.

Frequently Asked Questions about the 745-W2-P1-G1-HI-T-H

What makes the Multilin 745-W2-P1-G1-Hi-T-H unique compared to other transformer protection relays in the 745 series?

The 745-W2-P1-G1-Hi-T-H Multilin transformer protection series contains unique options that differ from other part numbers.

Notably, the “-H” option indicates that the relay has a harsh chemical environment conformal coating for operation in harsh environments.

The T option in the 745-W2-P1-G1-Hi-T-H Multilin Dual Winding Transformer Management Relay differs from other relays in the 745 system in terms of display and Ethernet.

Transformer protection systems without the T option have either a basic display (B) or an enhanced display (E) with a larger LCD.

The T option comes with an enhanced display, larger LCD, and 10Base-T Ethernet.

How does the 745-W2-P1-G1-Hi-T-H Multilin monitor and manage power transformers?

The 745 Multilin series is a series of transformer protection systems that have the ability to manage and protect power transformers.

For this reason they are known as transformer management relays. As with the other relays in the 745 series, the

745-W2-P1-G1-Hi-T-H is capable of using frequency, percentage difference, overcurrent and overexcitation protection elements as well as harmonic (single harmonic and total harmonic (THD)) tracking elements in one system.
