About the DS200PLIBG1A
The DS200PLIBG1A is a phase logic interface board designed by GE as part of their Mark V Speedtronic system. This board has been discontinued by the manufacturer but continues to be available through AX Control. It is a multi-input/output board with on-board RAM. This board is often used within the EX2000 digital regulator used for brushless excitation systems. This versatile Mark V Series product is additionally not considered the original printed circuit board product offering available to the Mark V Series; that would be the DS200PLIBG1 Phase Logic Interface Board missing this DS200PLIBG1A PCB's singular A-rated product revision.
Hardware Tips and Specifications
As explained above, this DS200PLIBG1A Phase Logic Interface Board is specifically definable as a Mark V Series product that exists within the EX2000 subseries of excitation control systems. EX2000 systems are designed to control ac terminal voltage or the reactive volt-amps through control of the rotating brushless exciter field. This brushless exciter field can be single-phase or three-phase. For a TMR turbine control panel, each servo-valve will have three coils, with one coil from each servo being connected to their corresponding <R><S><T> phases. Servos in the assembly of this DS200PLIBG1A Phase Logic Interface Boardare designed with a failsafe spring. Phase logic devices are designed as interfaces between batch execution servers and phase logic within the process controller. It is typically used to control state transitions for phases and the communication between these two areas.
The DS200PLIBG1A PCB featured here is an early phase logic interface, designed with multiple different connectors. These include six vertical pin connectors that are at the center of the board, placed parallel to each other. Additional connectors are located at the top and bottom of the board. Other board components in the assembly of this Mark V Series product offering include banks of LED indicators, integrated circuits, resistor network arrays, capacitors, and resistors. The board is drilled for mounting purposes and carries the GE logo, with edges additionally being marked marked for installation alignment. Additional information about the board may be found using original documentation material from General Electric like user guides and manuals. Before making a final purchase decision on this DS200PLIBG1A Phase Logic Interface Board, it is important to be cognizant of the fact that this particular Mark V and EX2000 Series printed circuit board is modified from its original functional status, dimensions, and performance specifications through the addition of its functionality-aimed single product revision, which is graded by the GE manufacturer at an A rating.
