DS200SHVIG1B GE MarkV, SCR High Voltage Interface Board

Description:

The DS200SHVIG1B from General Electric is a component of the Mark V series, specifically an SCR high voltage interface board. This board is part of the Mark V Turbine Control System series, designed to be compatible with various GE drives. It plays a crucial role in managing and controlling automated drive systems for wind, gas, or steam turbines that are GE-compatible. Despite its obsolescence due to discontinued production by General Electric years after its initial release, the Mark V series remains highly sought after, especially for its use of the patented Speedtronic control system technology first introduced with the Mark I series in the mid to late 1960s. The DS200SHVIG1B is not the original product of its specific functional role within the Mark V series; it represents a later development with enhanced features.

Hardware Features and Specifications

This board serves as an interface between the SCR bridge and the power supply, facilitating communication with the drive's current power connect card (PCCA), instrumentation card, and power supply. It processes voltage signals ranging from -500 mV to 500 mV, converting them into differential frequencies between 0 and 500 kHz for the drive's power supply. User configurability is a key feature, with seventeen jumpers allowing for customization according to user requirements. Each jumper enhances the board's attenuation capabilities, equipped with 10:1 current transformers. Three onboard LED indicators alert users to any blown filter fuses. The board employs standardized voltage-limiting hardware components like capacitors, resistors, diodes, and specialized integrated circuits for voltage suppression and limitation.

Given its status as an obsolete legacy product, instructional manuals for the DS200SHVIG1B  are scarce. However, its functional product number provides insights into its hardware details, including its dual-functional DS200 series tag, normal PCB coating style, group one Mark V series product grouping, primary and secondary functional revisions (B-rated and G-rated), and artwork configuration revision (D-rated).

Safety is paramount when handling this high voltage board. Only qualified personnel familiar with GE boards and drives should operate it. For detailed wiring and installation instructions, refer to the device's manual and datasheet. Originally, members of the Mark V series, including the DS200SHVIG1BGD, received technical support directly from General Electric.

Frequently Asked Questions:
1.Where is DS200SHVIG1B mounted?
DS200SHVIG1B is mounted on the drive's SCR cell assembly. DS200SHVIG1B is mounted on six nylon standoffs and six nuts are used to secure DS200SHVIG1BGD to the standoffs.

2.What is voltage range for DS200SHVIG1B ?
Voltages that range between -500 mV and 500 mV can be processed by the card. These mV inputs are converted by DS200SHVIG1B into differential frequencies ranging between 0 ando 500 kHz.
