About the DS2020FECNRX001A
This DS2020FECNRX001A Field Exciter Board, as mentioned above, was originally manufactured for use in General Electric's Mark V Series of turbine control systems. This DS2020FECNRX001A model of Field Exciter Board is not considered to exist as the original Mark V Series Field Exciter Board product, however, as this DS2020FECNRX001A printed circuit board is modified from the original Mark V Series product offering through the use of at least one significant functional product revision. In addition to this, this DS2020FECNRX001A PCB is considered to possess a special assembly version, given the presence of the DS2020 series tag in the DS2020FECNRX001A functional product number.
Hardware Tips and Specifications
As with any Mark V Series product, this DS2020FECNRX001A Field Exciter Board has its own set series of hardware inclusions and specifications, beginning with its customizable hardware. The GE Field Exciter Board DS2020FECNRX001A features 7 jumpers and 2 terminal blocks with 3 terminals on each. These jumpers are identified as JP1 through JP7. The GE Line Protection Board DS2020FECNRX001A also contains multiple prong-type connectors, and is installed on standoffs on another component of the drive. The signal wires that connect to the DS2020FECNRX001A board originate on the component to which it is attached. The DS2020FECNRX001A board featured here is populated with four capacitors, and they require some consideration before you handle the board due to the risk of electric shock from the high-voltage stored in the capacitors. During normal processing, the board is exposed to high-voltage, with capacitors storing any excess voltage until instructed to release the current to other components on the board. Most components do not store voltage and when the voltage is removed from the board, the components are also free of voltage. However, capacitors store voltage and so are a danger to individuals who touch the board when power is removed. The 2 fuses on the board protect the board from damage if the board receives too much current. The fuses are rated to blow if a specific threshold is exceeded. For that reason, if you replace the fuses, only install fuses with the same rating. If you install fuses with a different rating the fuses might allow current to damage the board. This DS2020FECNRX001A Board operates using one of two possible field supplies; either non-plugging or plugging field supplies, shortened to NRX or NRP nomenclature labels.
