GE DS200NATOG3A Voltage Feedback Scaling Board

Configured for voltage attenuation and feedback derivation in GE LCI drive control systems, the GE DS200NATOG3A (DS200NATOG3A Voltage Feedback Scaling Board) provides direct scaling of SCR bridge AC and DC voltages for control and monitoring functions. The board processes high-voltage feedback signals through configurable resistor networks and supplies conditioned voltage references to associated control assemblies within the LS2100 platform.

Hardware Specifications

Voltage Feedback Scaling Architecture

The DS200NATOG3A is designed to attenuate SCR bridge voltages so that accurate voltage feedback signals can be generated for control system processing. The board receives AC and DC voltage inputs and scales them through precision resistor networks before transmitting the conditioned signals to associated control hardware.

Five independent resistor strings are provided within the board architecture. Each resistor string incorporates three selectable stab connectors, allowing input voltages to be matched to the required attenuation network. This arrangement enables support for multiple bridge voltage configurations while maintaining consistent feedback scaling characteristics.

The board functions exclusively as a feedback conditioning assembly and relies on associated gate distribution and VME backplane hardware for complete system operation.

Firmware Compatibility and Control System Integration

Within the LS2100 drive architecture, the DS200NATOG3A operates as a dedicated voltage feedback interface board. The module is intended for use with compatible bridge interface circuitry and associated control hardware.

Because the DS200NATOG3A is identified as a unique catalog designation, replacement boards should match the specified part number to maintain hardware compatibility within the installed system configuration.

Frequently Asked Questions

Q: Can the resistor strings be configured for different voltage levels?
A: Yes. The resistor strings can be configured for 1200 V, 2200 V, 3300 V, 4200 V, and 6900 V input applications.

Q: Is the DS200NATOG3A backward compatible with earlier NATO boards?
A: No. The documentation identifies the DS200NATOG3A as a distinct board version that is not backward compatible.

Q: What additional boards are required for operation?
A: The board operates in conjunction with a VME backplane board and a gate distribution status board.

Field Installation Guidelines

• Verify the exact board part number before replacement.

• Confirm stab connector selection matches system voltage.

• Inspect resistor strings for physical damage before service.

• Ensure ribbon cable connections are fully seated.

• Isolate cabinet power before installing or removing the board.
