The DS200SHVIG1B manufactured by General Electric is an SCR high-voltage interface circuit board within the Speedtronic Mark V Turbine Control System lineup. Compatible with all GE drive units, this PCB serves as a signal intermediary between input voltage signals and drive power supplies. It facilitates signal transmission among the PCCA power connection card, power supply modules and instrumentation boards. The Mark V platform, which this board belongs to, is widely applied in automated control and monitoring systems for gas, steam and wind turbine drive equipment.

Holding high market recognition in industrial automation, the Mark V Series stands among GE’s last generations built around proprietary Speedtronic control technology, which has long underpinned the brand’s turbine control product portfolio.

Like all new and refurbished Mark V series PCBs in our inventory, the DS200SHVIG1B is engineered with dedicated hardware components tailored to its designated control functions. Its core responsibility is converting and forwarding analog voltage signals: the board accepts input signals from -500 mV to 500 mV, then converts them into differential frequency signals spanning 0–500 kHz, which are subsequently transmitted to the drive power supply for corresponding operational adjustments.

High configurability is embedded in its design. Seventeen configurable jumpers are integrated to deliver flexible signal attenuation, paired with 10:1 current transformers for circuit protection. Three onboard LED indicators trigger alerts whenever any built-in filter fuse blows. Standard voltage regulation and surge suppression are implemented via onboard electronic components including rectifiers, capacitors, diodes and integrated circuits. Note that the DS200SHVIG1B is an upgraded derivative, not the original baseline SCR high-voltage monitoring board for the Mark V system.

Strict adherence to official installation standards is mandatory to guarantee stable performance of both the board and matched drives. Precise wiring is critical for reliable system operation; full wiring diagrams and operational guidance are documented in the official manual and datasheet. General Electric originally supplied full technical after-sales support for all original and replacement Mark V series circuit boards.

As official digital documentation for this part is limited online, the full part number DS200SHVIG1B acts as a key reference to decode its hardware specifications, with each character segment representing distinct product attributes:
