GE Mark V DS200CTBAG1ADD Analog Output Terminal Board

Product Technical Overview

The General Electric DS200CTBAG1ADD is a specialized Analog Output Terminal Board designed for the Mark V Speedtronic Turbine Control System. This hardware serves as the physical interface between the SDCC Drive Control Board and external field devices. It is engineered to facilitate the precise distribution of analog signals required for turbine regulation, auxiliary control, and feedback loops. As a legacy component, this board is critical for maintaining the operational integrity of existing Mark V control architectures.

Functional Specifications and Hardware Interface

The DS200CTBAG1ADD acts as a termination point for wiring, ensuring signal stability and shielding for sensitive analog outputs.

• Model Identification: DS200CTBAG1ADD

• System Compatibility: GE Speedtronic Mark V Control System

• Primary Interface: Connects directly to the SDCC (Drive Control Board) via ribbon cables

• Signal Support: Manages multiple analog output channels typically used for valve positioning and motor speed references

• Protection: Integrated terminal blocks for secure field wiring and noise reduction

• Board Revision: G1 revision with ADD functional suffix

• Physical Weight: 0.45 kg (1.00 lbs)

Operational Application

This terminal board is primarily utilized in power generation and heavy industrial environments where the Mark V system controls gas or steam turbines. It facilitates the conversion of digital control logic into the physical current or voltage signals (such as 4-20 mA or 0-10V) needed to drive actuators and positioning systems. Due to its legacy status, it is often sourced for system maintenance, hot-swap repairs, or the extension of existing control cabinets.

Frequently Asked Questions

Is the DS200CTBAG1ADD a standalone controller?

No, it is a terminal board. It requires a Drive Control Board (SDCC) or a similar processing card within the Mark V rack to function.

Does this board support digital I/O?

While specifically designated as an Analog Output Terminal Board, the Mark V system uses other boards in the CTBA series for digital inputs/outputs. This specific model focuses on analog signal distribution.

Can I replace a DS200CTBAG1A with this ADD version?

The "ADD" suffix indicates specific functional enhancements or hardware revisions. Always verify your system's configuration files (IOCFG) before swapping revisions to ensure software compatibility.
