Product Overview of DS200DDTBG2ABB
DS200DDTBG2ABB functions as an LCI auxiliary input/output terminal printed circuit board, a dedicated hardware part designed for GE Mark V turbine control platforms. The Mark V platform belongs to GE’s Speedtronic gas and steam turbine control lineup, being the second generation to deploy triple modular redundancy for core control loops and safety protection logic. The Mark V product ecosystem this PCB belongs to comes equipped with native diagnostic tools, hot-service maintainability, and direct signal connection ports for field sensors.
It is worth noting that DS200DDTBG2ABB is not the base version of the LCI auxiliary I/O terminal card for Mark V turbine systems. Its baseline model is DS200DDTBG2, which lacks the three major revision upgrades integrated into DS200DDTBG2ABB.
Hardware Specifications & Operational Notes
Classified as a high-voltage circuit board, DS200DDTBG2ABB serves as the signal hub for all auxiliary I/O links within the turbine control system. To fulfill this high-voltage signal transmission task, the board is assembled with specialized hardware components tailored for stable signal operation. Power supply and communication links for DS200DDTBG2ABB are routed via DS200ADMA, a sub-board mounted onto the DS200DSPC digital signal processor main control card. This terminal board integrates abundant input and output signal channels of diverse types.
Input Channel Configuration
- 2 high-voltage AC input channels
- 6 high-current signal input channels
- 3 low-current signal input channels
- Maximum 2 channels of 4–20 mA analog loop inputs
- Multi-purpose universal voltage input terminals
On this LCI auxiliary I/O board, onboard jumpers allow engineers to reallocate CT or LEM dedicated channels to serve as 4–20mA loop inputs. For output circuits, the card carries four buffered analog output ports plus two independent 4–20mA current output channels, alongside 16 universal digital I/O points.
Test Indicators, Jumpers & Electronic Components
- 33 TP test terminals for on-site signal measurement and troubleshooting
- 17 status indicator LEDs, numbered DS1 through DS17
- 12 three-position jumper switches; factory default setting is pins 1–2
Standard voltage suppression and signal processing components fitted on the board include:
2 isolation transformers, 4 electromagnetic relays, 14 transistors, various capacitors and discrete resistors.
The entire PCB assembly is protected with standard chemical conformal coating for environmental resistance. Additional built-in components consist of 8 varistors and 15 integrated resistor network packs. Five terminal blocks with varying screw terminal counts (ranging from 3 to 36 positions) are mounted for field wiring connection. Multiple integrated chips are also populated on the board, including an identification IC storing part number and hardware revision data.
Supporting Documentation & Purchase Reminder
GE’s official manual GEI-100219 contains full installation guidelines, functional descriptions, application scenarios and performance parameters for this hardware. As Mark V is a legacy turbine control product line, this technical document is not easily accessible via public online channels.
One critical detail to check before purchasing DS200DDTBG2ABB: this variant incorporates three rounds of revisions (two functional upgrades plus one PCB layout revision). These modifications have altered the original factory dimensions and performance metrics of the base DS200DDTBG2 board, which must be considered during equipment matching and replacement.
