GE DS200RTBAG2A

Overview

Relay switching is essential for coordinating control commands and auxiliary equipment in industrial excitation systems. The GE DS200RTBAG2A is an RTBA relay terminal board designed for compatible GE EX2000 excitation and turbine control applications.

It contains multiple electromechanical relays that provide switching contacts for external control circuits. In addition, configurable jumpers allow technicians to adapt the board to the requirements specified for the installation.

Functional Design

The board contains ten relays in two contact configurations. Seven relays use double-pole, double-throw (DPDT) contacts, while three use four-pole, double-throw (4PDT) contacts. MOV components provide transient protection for the relay circuits.

Its main functions include:

• Switching auxiliary control signals.
• Supporting relay-based interlocking arrangements.
• Providing additional contacts for compatible excitation systems.
• Connecting relay circuits with associated control hardware.
• Supporting maintenance through accessible connections and status indicators.

Industrial Uses

The board can be used in generator excitation cabinets, turbine control installations, and industrial drive systems that require relay-based signal switching. It helps connect control logic with external circuits while supporting organized cabinet integration.

Replacement Guidance

When sourcing a replacement, match the complete part number and verify the coil voltage and contact arrangement. Before energizing the equipment, confirm that all jumper positions and wiring connections match the original configuration. Qualified technicians should perform installation and operational checks.
