The DS2020LRPAG1 is a Resolver Module made for General Electric’s Speedtronic Mark V series of turbine control systems. The DS2020LRPAG1 is a legacy series and is no longer receiving any support from GE.
The DS2020LRPAG1 is 115/230 VAC and is single-phase. It is protected by a metal chassis. The bottom of the chassis is open, exposing the internal circuit board. On the sides are four factory drilled holes, one in each corner, that enable this unit to be vertically mounted onto a flat surface. This chassis should only be mounted into an indoor environment that is free from excessive dust, corrosive materials, and liquids. On the front face of this chassis are two large metallic screws that can be used to fully expose the internal circuit board.
The bottom edge of the circuit board of the DS2020LRPAG1 is less protected than the rest of the components. This edge has on the bottom left corner an RS-232 connection that is above a relay. Around these two components are eleven red varistors. Below the varistors are two resistors. On the center of the bottom edge is a red and white inductor coil. In the bottom corner of the board is an integrated circuit.
For more information about the DS2020LRPAG1, please consult the General Electric produced product manuals, datasheets, and application guides. Due to the integrated circuits, be sure to observe antistatic procedures to prevent any type of system damage to the DS2020LRPAG1. Only trained professionals should attempt to install this unit into a Mark V control system.
