Product Description
Originally manufactured for the EX2100 series of Excitation Control Systems and Excitation Control System component products; this IS200EDCFG1BAA module PCB is a revised printed circuit board; featuring a functional revision 1 rated at a "B" grade, a functional 2 revision rated at an "A" grade, and an artwork revision rated at an "A" grade as well. These three revisions modify this part from its original IS200EDCFG1 parent product, which is explicitly definable as an Exciter DC Feedback Board. This functional description is backed through this product's EDCF functional acronym, which in this instance happens to line up exactly with each letter.
Hardware Tips and Specifications
The IS200EDCFG1BAA Exciter DC Feedback Board features a number of crucial, product-specific hardware features that all contribute to its overall functionality. To fully understand all of the hardware components included in this printed circuit board's unique configuration assembly, it is firstly important to understand the function of the product. The IS200EDCFG1BAA EDCF board is used to measure both field current and voltage for the overall EX2100 series drive assembly's SCR bridge. This IS200EDCFG1BAA product also serves to interface with a corresponding EISB board, through the use of a high-speed fiber-optic link connector. This process is regulated in part through this EDCF-abbreviated board's inclusion of a singular LED indicator, which indicates the corrective operation of the board's power supply. This LED is labeled with the factory-printed nomenclature PSOK, and glows green to indicate regular PCB function.
Beyond the basic functioning and singular LED indicator apparent to this IS200EDCFG1BAA model PCB, the EDCF board offers a number of jumpers and connectors for supreme customization and compatibility purposes. One of the more crucial connectors established on the base board of this PCB exists in its J16-labeled connector, which establishes an input voltage connection of 24 V dc into the board assembly. The two Fiber-optic cable connectors included in the IS200EDCFG1BAA board's configuration assembly include both the CF OF-labelled Field Current Feedback Pulse connector, as well as the similar VF OF-labelled Filed Current Feedback Pulse connector. Both of these connectors can be classified as HFBR-1528 fiber optic drivers, specifically. Some of the jumpers more relevant to this EDCF board include a series of eight total Bridge Voltage Scaling Jumpers, intended for different PPT voltages ranging from 140 V rms to 1400 V rms. An external power supply is required to provide sufficient voltage to the IS200EDCFG1BAA board; this source is classified as a 24 VDC set of voltage regulators. All of these previously-mentioned hardware components should be sufficiently protected beneath a solid layer of chemically-applied normal PCB coating, as evidenced by the "G1" series grouping tag present in the IS200EDCFG1BAA functional product number.
