DS200PTCTG1ABC

Product Description

The DS200PTCTG1ABC functions as a Potential Transformer Current Transformer (PTCT) board.  It is used to isolate and scale voltages and current signals from CTs and PTs.   The board also offers auxiliary inputs for the Mark V system for low voltage current signals.  After signals are isolated on this board they are sent to the TCCB transducer board. 

  The JKK ribbon connector mounts from this board to the TCCB board, and passes secondaries of the isolation transformer.  Additionally, the board accepts one of three sets of 3-phase PT inputs entering the system.   These PT inputs are used by the control system as an optional voltage matching feature.  

The DS200PTCTG1ABC board features four individual terminal strips lined up along one long board edge.  Most of the terminal connectors on these are individually labeled along the board surface, but not all.  On the opposite side of the board there is a single vertical connector for the JKK ribbon connector.    Other board components sit between these components, and include six transformers in frames and three toroidal transformers, along with several jumper switches, an AD202JY isolation amplifier, resistor network arrays, resistors, and capacitors.   The board is marked with the General Electric logo, with its board identification number, and with several codes that should help with installation.   For additional help with installing this board, refer back to original GE documentation like manuals and user guides.  This is especially important with boards like this one where voltages may be present even after mains power has been removed.
