GE DS200RTBAG1AHC

Product Overview

The GE DS200RTBAG1AHCis a Relay Terminal Board belonging to the GE Mark V Speedtronic control platform. It is used to provide relay signal termination and interface functions between the control system and external field circuits. The exact part number is identified by multiple industrial automation suppliers as a Mark V relay terminal board.

The board is particularly relevant to maintenance and replacement projects involving legacy GE turbine-control equipment, where maintaining the original Mark V architecture is important.

Available product references identify the DS200RTBAG1AHC specifically as a relay terminal board and associate it with GE Mark V turbine-control systems.

Main Features

The board is designed to support reliable handling of discrete relay-related signals within the control system. Its primary characteristics include:

• Relay signal termination
• Interface between control logic and external circuits
• Compact PCB construction
• Suitable for industrial control cabinets
• Designed for GE Mark V system integration
• Practical solution for legacy system maintenance
• Supports organized field wiring and relay connections

The board's role is primarily concerned with signal interfacing rather than high-level controller processing, making it an important supporting component within the overall control architecture.

Hardware and Signal Interface

The DS200RTBAG1AHC provides a physical interface for relay-related field signals. In a typical installation, signals from the control system are routed through the terminal board to external devices or circuits.

The PCB-based design allows multiple signal connections to be arranged within a relatively compact assembly. This makes troubleshooting and replacement more manageable compared with individually wired relay circuits.

It is worth noting that some online listings attribute additional communication functions or detailed electrical specifications to this model, but these claims are not consistently supported by authoritative documentation. For engineering replacement purposes, the safest identification is GE Mark V Relay Terminal Board, DS200RTBAG1AHC.

Typical Applications

The DS200RTBAG1AHC can be found in industrial systems where GE Mark V control equipment is still operating, including:

• Gas turbine control systems
• Power generation facilities
• Industrial turbine installations
• Generator auxiliary systems
• Legacy GE Speedtronic equipment
• Industrial relay-control applications

The Mark V platform remains relevant in many maintenance environments because replacing an entire turbine control system can require substantial engineering work and downtime.

Installation and Maintenance

Before installing a replacement DS200RTBAG1AHC, technicians should verify the complete part number and revision information on the original board. Field wiring should be documented before disconnection to avoid incorrect signal termination.

During maintenance, inspect terminal connections, relays, wiring, connectors, and the PCB for signs of overheating, corrosion, loose connections, or physical damage. Any associated external relay or field device should also be checked when a repeated signal fault occurs.

Because the board is part of an industrial turbine-control system, installation and testing should be performed by qualified personnel following the applicable GE system documentation and site safety procedures.
