About the DS200ACLEH1

The DS200ACLEH1 is a Mark V board component.  This board typically mounts within an EX2100 exciter board rack or within a standard Innovation series drive. The Mark V was one of the last of the Speedtronic systems to be released by GE, although it was only the second of the series to offer a triple modular redundant architecture. While the Speedtronic control system technology adopted in various products of the Mark V Series can be considered up to date, the Mark V Series as a whole must be considered a now-obsolete legacy product series due to its eventual manufacturing discontinuation that took place in the many years since its initial conception. The MKV also has available online maintenance, direct sensor interface, and built-in diagnostics that allow faults to be identified down to the board level for the panel. This DS200ACLEH1 PCB exists as the original Mark V Turbine Control System Series product of its intended functionality, as evidenced by its DS200ACLEH1 functional product number's lack of any revision-indicating trailing digit.

Hardware Tips and Specifications

The DS200ACLEH1 functions as a Hub LAN Driver Card. This is an application control layer board that is sometimes used with an added PC/104 ISBus extension board to create a control layer module that can perform multiple duties over the MKV communication networks. The DS200ACLEH1 can communicate with various parts of the MKV system, including the Control System Toolbox (via TCP/IP) and the CIMPLICITY graphics software (via Ethernet.) The DS200ACLEH1 is populated by various components on its rectangular surface, including a read-only chip with the board’s serial number, major and minor revision record, and board catalog number. The board has an onboard timer (programmable) that will produce a periodic time signal to the DSPX board through a LAN signal carried via the P1 connector. Other  components include a CPU chip, a header connector to connect to the optional board component, various vertical pin ribbon connectors (male and female) transistors, resistors, diodes, and capacitors. For a more complete picture of the DS200ACLEH1 board, please refer to data sheets, user guides or manuals originally published by General Electric. 

Unfortunately for the sake of this DS200ACLEH1 PCB's personalized product page, this DS200ACLEH1 printed circuit board, as mentioned above, was originally manufactured for placement in a General Electric legacy product series, and because of this, it is not well-detailed in any internet-available instructional manual documentation. With this being the truth, it is a good thing that this DS200ACLEH1 product offering was manufactured by General Electric, as the esteemed manufacturer paired it with its own DS200ACLEH1 functional product number detailing a number of basic and important hardware specifications in several functional naming chunks. For example, the DS200ACLEH1 functional product number begins with the DS200 series tag delegating this DS200ACLEH1 device's normal Mark V Series assembly version as well as its domestic original manufacture location. This dual-functional tag is followed in the DS200ACLEH1 functional product number by the ACLE functional product abbreviation, which itself is followed by the H1 series grouping tag. Much like the aforementioned DS200 series tag, this H1 series grouping tag has dual naming responsibilities, dictating this DS200ACLEH1 Board's conformal coating style and its group one Mark V Series product grouping. The lack of any trailing alphanumeric digits on the DS200ACLEH1 functional product number is telling of this DS200ACLEH1 PCB's lack of any significant product revision. This DS200ACLEH1 product's initial classification as a Hub LAN Driver Card is not all too surprising, as its Mark V Series card status is encouraged through its relatively-small basic dimensions as well as its crucial role in Mark V Turbine Control System Series automated drive assembly LAN communications processes. As mentioned above, no significant revision has been made to this DS200ACLEH1 device's normal assembly.
