Product Description

This IS200EDFFH2AAA DC Fanned Feedback Board was manufactured by General Electric shell company GE Industrial Systems for use within the greater EX2100e series of excitation control systems and excitation control system component products. This printed circuit board is unique, as it is considered a dual-system printed circuit board; while simultaneously not featuring a special assembly type. The dual-system style inherent to this EDFF-abbreviated DC Fanned Feedback Board is revealed through its functional product numbers' inclusion of the "H2" series grouping tag, which defines the part as both a conformally-coated circuit board and as a member of the EX2100 series' group 2 series grouping. This is a revised version of the original IS200EDFFH2 parent board; boasting two functional revisions and a single artwork revision all rated at "A" grades.

Hardware Tips and Specifications

This IS200EDFFH2AAA module PCB features numerous hardware components specific to its intended function as a DC Fanned Feedback Board. For starters, this GE Industrial Systems printed circuit board is essentially comprised of two separate halves of nearly-identical components. This model DC Fanned Feedback Board makes use of two V-F or voltage-to-frequency converter circuits; intended for field current and field voltage feedback applications. The measurement of the IS200EDFFH2AAA board's applicable field currents is done primarily through the use of a shunt located in the board assembly's dc field circuit. A fiber-optic link is available, extending from the base board of this IS200EDFFH2AAA model, and is intended to provide connection to the compatible EAUX processor board; aiding in high-noise immunity attainment processes. 

A number of other important hardware components and specifications concerning this IS200EDFFH2AAA model PCB can be discovered upon the conduction of a thorough IS200EDFFH2AAA part number breakdown, considering the functional status of the IS200EDFFH2AAA part number and all other EX2100 series component parts. The IS200 tag present at the very beginning of this individualized part number speaks to this product's status; both as a domestically manufactured GE part, and as an EX2100 series component without a special assembly version. An inclusion of the EDFF functional acronym is followed quickly by the "H2" series grouping tag in the IS200EDFFH2AAA product number. This H2 tag has dual functionality as well; detailing this DC Fanned Feedback Board as a dual-system group 2 series product with a conformal-style protective PCB coating. The final three "A" digits present in the unique IS200EDFFH2AAA product number are representations of the three significant product revisions made to the IS200EDFFH2AAA DC Fanned Feedback Board.

Frequently Asked Questions about IS200EDFFH2AAA

Is the meaning of this IS200EDFFH2AAA product's H2 series grouping known?

While this product's grouping within the greater EX2100 Series as a Group 2 product is known, the original meaning of this designation has been lost. It most likely refers to an individual hardware component's inclusion or omission within the greater IS200EDFFH2AAA board assembly.

Are this IS200EDFFH2AAA DC Fanned Feedback Board's three significant product revisions considered backwards-compatible?

No. While all three of this product's significant revisions are rated at "A" grades, only its first two functional product revisions are considered backwards-compatible.

Is EDFF really the factory-specified functional acronym for this DC Fanned Feedback Board?

Yes. Despite this DC Fanned Feedback Board's seemingly misaligned functional description, this board correctly corresponds with the EDFF functional acronym. Not all General Electric functional acronyms correspond directly with their product descriptions.

Reviews For IS200EDFFH2AAA

Internal Review

The IS200EDFFH2AAA printed circuit board or DC Fanned Feedback Board was originally mass-produced through the use of specialized General Electric manufacturer GE Industrial Systems. This product's specialized manufacturer makes sense when faced with this PCB's intended placement in the EX2100E series, a more focused, newer series than the general EX2100 series of Excitation Control System-oriented products. This printed circuit board comes equipped with a specialized series of voltage-to-frequency converter circuits; perhaps responsible for this device's inclusion of the chemically-applied conformal style of PCB coating. - AX Control Lead Technician
