About the IS200DSPXH1DBD

The IS200DSPXH1DBD is a printed circuit board (PCB) manufactured and originally distributed by GE as part of their Mark VI Speedtronic series. This series was developed as a control system for gas and steam industrial turbines, frequently used in energy systems. The IS200DSPXH1DBD PCB is specifically utilized in Innovation Series drives and EX2100 exciters.

This module is a significant functional upgrade over the prior industry-standard Mark V Turbine Control System Series, expanding applications to include wind turbines alongside gas and steam turbines. The Mark VI Series, including the IS200DSPXH1DBD, is also noted for being among the last Mark Series to incorporate the patented Speedtronic control system technology across multiple products.

Hardware Overview and Features

• The IS200DSPXH1DBD is a compact rectangular board featuring an attached front faceplate.

• It functions as a Digital Signal Processor Control Board, incorporating a digital signal processor connected to an ASIC (Application-Specific Integrated Circuit) that executes custom logic functions.

• Onboard firmware is stored in flash memory.

• Multiple input/output connectors are present, including two on the front faceplate.

• The front faceplate houses two LED indicators (green and red) to signal processor alarms.

• The board connects to the rack via a right-angled backplane connector supporting:

• Data bus

• Address bus

• Control output signals

• Keypad interface

• Tool interface

• VCO inputs

• The board is static-sensitive; handling requires grounding straps to prevent damage.

• Removal or replacement should only be done when the rack is de-energized.

• Installation must be performed by qualified personnel following GE’s official manuals or datasheets.
