The DS200DSPCH1ADA is a GE digital signal processor control board compatible with GE’s Mark V Speedtronic control system for steam and gas industrial turbines. The DS200DSPCH1ADA provides the communication bandwidth and processing power to directly control the system’s power converter applications and high-performance drivers. The board has expandable inputs and outputs. The larger Mark V turbine control system family that this DS200DSPCH1ADA device belongs to is considered a legacy product family that is now obsolete, as it eventually ceased production many years after its initial release. This being the case, it can also be defined as one of GE’s final product lines to take advantage of the brand’s patented Speedtronic control system technology, which was first offered in the late 1960s along with the original version of the Mark V series. This DS200DSPCH1ADA PCB is not the original product of its intended Mark V series features; This will be missing the DS200DSPCH1ADA product with three important product revisions to the DS200DSPCH1 motherboard.

Hardware tips and specifications

The DS200DSPCH1ADA is a complex circuit board with multiple subboards. Given the ownership of this DS200DSPCH1ADA product, its DS200DSPCH1ADA functional product number does not mention a special Mark V series assembly version, which is somewhat unusual, as is the case with other typical Mark V Series motherboards. One board is mounted parallel to the board surface using a bracket and the other board is mounted vertically. One of the subboards is used to provide scaling, buffering, isolation, and conditioning of the signals so that they can be accessed and used by the DS200DSPCH1ADA digital signal processor. The DS200DSPCH1ADA has two backplane connectors on the back edge. The board is built from an additional front panel with multiple I/O and LED indicators. The panel also has a reset button and two setting screws (top and bottom) that help lock the board into place when installed into the rack system. Before replacing the mainboard, ensure that all power supplies to the drive are disconnected first. An incorrect installation program may result in personal injury. Each LED indicator in this DS200DSPCH1ADA printed circuit board product assembly has been affixed to the respective factory-printed naming label and is identified by reference to the DS200DSPCH1ADA instruction manual attached above. Some of the specific LED indicators that are important for the functional fault diagnosis function of the DS200DSPCH1ADA board include:

Green IMOK universal board function indicator
Red FAIL VME bus fault fault condition indicator
Amber LED1 indicator light
Amber LED2 indicator
Amber LED3 indicator
Amber LED4 indicator
