How to identify the GE turbine control card part number?
Time: December 09, 2025
GE turbine control card part consist of the letters and the number, always quite long. With the part number, we can know the card series and the functional revison. Then, how to identify the part number quickly?
The first 5 digits represent the series. Generally, DS200 belong to GE Mark V series, IS200 is Mark VI or EX2100 system, IS220 is Mark Vie series, the newest series, manufactured since 2004. IS420 also belong to Mark VIe series system. The number "200" or "220" means the assenble lever, 200 is a base lever board, 215 is a higher level assembly or added components, such as IS215VAMBH1A is a assembly board. The 6th to 9th digits of the model number indicate the card function, it is the functional acronym. The 10th digit reprensent the group, normal or conformal. The 11th digit, after the number, it is means the functional revision, not backward compatible. The last 2 digits represent the revision, the later an entry in the alphabet is, the newer the version. For example, DS200TCDAG1B, it is GE Mark V series card, TCDA represent digital I/O board. The letter G means normal coating. DS200TCDAG1BFD is newer revison than DS200TCDAG1BCB. IS200TBAIH1C is GE Mark V Analog Input Terminal board. IS200ERIOH1A is GE EX2100, Regulator MAIN I/O Card. IS220PDIAH1A belong to GE Mark VIe series, PDIA described as discrete input pack. "H" represent the conformal coating. Beside IS220PDIAH1A, we also have the stock of IS220PDIAH1B, 1B can't backward compatible to 1A.
GE part number usually printed near the edge of the board. The part number including so much information about the board, we can know identify them with a glance.
