About the DS200PTBAG1ABA
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.
- 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)
- (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. Many of this DS200PTBAG1ABA product offering's originally-introduced performance and hardware specifications are unobtainable due to their placement in unavailable and uncommon Mark V Series instructional manual materials. With this being true, however, the DS200PTBAG1ABA functional product number that the DS200PTBAG1ABA PCB possesses was specifically formulated by the original GE manufacturer to code for some of this DS200PTBAG1ABA product offering's more basic hardware details. The DS200PTBAG1ABA functional product number begins with the DS200 series tag delegating this DS200PTBAG1ABA PCB's domestic location of original manufacture, along with its normal Mark V Series assembly version. This dual-functional initial tag is followed in the DS200PTBAG1ABA functional product number by the PTBA functional abbreviation, which itself is followed by another dually-responsible naming component in the G1 series grouping tag. This grouping tag delegates the DS200PTBAG1ABA PCB's status as a normally-coated Mark V Series printed circuit board device with a group one Mark V Series product grouping. The final three alphanumeric digits present on the end of the DS200PTBAG1ABA functional product number are telling of this DS200PTBAG1ABA device's three-fold product revision history.
