Overview

The DS200SHVMG1AGE is a High Voltage M-Frame Interface Board developed by General Electric for the Mark V turbine control system series. It is designed for use in a variety of GE exciters and drive systems, providing an interface across the drive architecture.

This board enables communication between the power supply board (DCFB or SDCI) and the power connect card (PCCA) with the SCR bridge found on M-frame drives. As part of the now-discontinued Mark V Series, it is among the final GE product lines to utilize the Speedtronic control system technology, which was introduced in the late 1960s.

Note: This board includes three revisions: two functional revisions and one artwork revision. These may affect the product’s dimensions and performance characteristics.

Hardware Features and Functions

The DS200SHVMG1AGE includes a range of hardware components and specifications designed to support efficient drive operation:

• Signal Conversion:
  Converts shunt signals from –500 mV to +500 mV into differential frequency outputs ranging from 0 to 500 kHz via onboard voltage-controlled oscillator (VCO) circuits.

• Input Integration:
  Receives input from DC positive and negative shunts, with frequency outputs transmitted to both the DCFB/SDCI power supply board and the PCCA power connect card.

• Current Attenuation:
  AC line current passes through a 10:1 current transformer (CT) to adjust incoming current levels.

• Selectable Jumpers:
  Features 17 jumpers for configurable attenuation settings based on specific drive requirements.

Plug Connectors

The board integrates eight plug connectors for streamlined, voltage-safe connections with other Mark V components:

• Connectors Included:

• CT1PL, CT3PL, DC1PL, DC2PL, 1CPL, SQPL, IA1PL, IA2PL

• 1CPL Connector Breakdown:

• 1CPL-1: L1 ACCT White Current Output

• 1CPL-2: L1 ACCT Red Current Output

• 1CPL-3: L3 ACCT Red Current Output

• 1CPL-4: L3 ACCT White Current Output

These designations are based on factory labeling, signal type, board location, and color coding for signal identification.

Installation and Safety

• Installation Requirements:
  Proper installation according to GE’s safety and configuration guidelines is essential to avoid equipment damage and ensure safe operation.

• User Guidance:
  A detailed illustrated wiring guide is available in the board’s instruction manual (GEI-100174) and datasheet.

• Support:
  Original technical support for this board and the broader Mark V series was provided by General Electric.
