DS200PTBAG1ABA

Product Description

The DS200PTBAG1ABA circuit board fits into General Electric’s Mark V Speedtronic turbine control system.  The MKV is just one of several Speedtronic turbine control systems released by GE since the 1960s, designed to protect, manage, and control industrial gas and steam turbine systems.   AX Control maintains on-hand replacement stock of many Speedtronic components for all of these systems, offering users a reliable source of these products that can no longer be sourced directly from the OEM. 

The DS200PTBAG1ABA functions as a protection termination module.  It is located within the <P1> core and terminates signals for that core.   Input signals like flame detection, generator/bus voltages, high and low-pressure shaft speeds, and generator currents land on the PTBA board.  Afterward, they are written to the TCEB board that also is situated in the <P1> core or to the TCQE board in the <R1> core.   Additionally, the PTBA board has a jumper that powers an audible horn alarm on the TCEB board.  To silence this, the J1 jumper should be removed. 

The DS200PTBAG1ABA has several connector options including plugs and vertical pin connectors.  These are used to read and write generator breaker signals (JM) and (JN), write emergency Overspeed signals (JU), write generator and bus voltage signals (JV), and carry 335VDC to the flame detection devices (JVA).   Another connector, (JJS/T) is typically left unused. 

GE manuals will provide additional important information about this board, including information regarding hardwired trips and primary overspeed protection.  Refer to GE manuals for installation and handling instructions.
