IS200ESELH2AAA

Product Description

This IS200ESELH2AAA printed circuit board was manufactured by GE Industrial Systems for use specifically in their EX2100 Series of Excitation Control Systems and Excitation Control System component products. This printed circuit board is more accurately definable as a EX2100 Exciter Selector Board, and is modified from its original IS200ESELH2 parent board status through its inclusion of three A-rated significant product revisions. 

Hardware Tips and Specifications

The IS200ESELH2AAA EX2100 Exciter Selector Board is primarily describable through its intended functionality within the greater EX2100 Series drive assembly. This IS200ESELH2AAA PCB is created with the intention of acting as a receiver for six logic level gate pulse signals, which are emitted from its corresponding EMIO board. The gate pulse signals that this ESEL-abbreviated board receives drive up to six total cables, which should then distribute to their own corresponding exciter gate pulse amplifier or EGPA boards, which should themselves be mounted in the EX2100 drive assembly's power conversion cabinet. In terms of this ESEL-abbreviated board's compatibilities, the number of ESEL boards required for normative function of EX2100 drive assemblies depends on the control systems type being used; redundant or simplex. If redundant controls are active within your EX2100 drive assembly, two IS200ESELH2AAA EX2100 Exciter Selector Boards are necessitated; one being driven by M1 and the other being drive by M2. This board assembly's active ESEL, which is selected by its C controller, transmits necessary control signals to the ESEL's corresponding EGPA boards. 

While original instructional manual materials surrounding this IS200ESELH2AAA PCV provide us with valuable insights into its hardware and performance specifications, additional information can be revealed through a diligent breakdown of the unique IS200ESELH2AAA product number, which would begin with the dually-functional IS200 series tag. This series tag has dual naming functionality for this ESEL-abbreviated PCB; identifying it as a domestically-manufactured product with no special assembly version. Another notable hardware specification retrieved from the customized IS200ESELH2AAA product number can be described as its H2 series grouping tag, which also has dual IS200ESELH2AAA naming responsibilities. This H2 series grouping tag defines this PCB as a conformally-coated printed circuit board with three total bridge drivers in its assembly. The three final "A" digits in the IS200ESELH2AAA product number detail this part's three-fold revision history.
