4. Product Introduction (Anti-Template)
The DS200CTBAG1ADD is an Analog Termination Module (CTBA) used in GE Mark V Speedtronic turbine control systems. It is typically installed in the core and serves as the primary landing point for analog field signals.
The board terminates 4–20 mA input and output signals, shaft voltage and shaft current signals, and provides the necessary connections for IONET communication to the STCA board and COREBUS links. It includes terminal strips for field wiring and multiple board-to-board connectors. A bypass relay on the board helps maintain COREBUS communication if power to the CTBA is lost. The module is a critical interface between field devices and the Mark V control processors in both Simplex and TMR configurations.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full part number (DS200CTBAG1ADD), revision markings (A/D), connector condition, and terminal strip integrity. Photograph all labels.
- Live Rig Testing – Install in a compatible Mark V core or test fixture, apply power, and verify basic connectivity, COREBUS/IONET links, and signal path continuity where possible.
- QA & Packaging – After inspection, protect all connectors and terminals, clean the board, and pack in anti-static protective packaging with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial control circuit boards. Packaging must protect against electrostatic discharge and mechanical shock; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
Core Location – The board must be installed in the correct core position (). Incorrect placement breaks IONET and COREBUS communication.
Connector Orientation – Ribbon and pin connectors (JAI, JAJ, JAA, 8PL, etc.) are polarized. Forced or reversed insertion can damage pins or the mating board.
Signal Type Matching – The CTBA is designed for specific 4–20 mA and shaft signals. Connecting incorrect signal types can damage the board or produce false readings.
Revision Compatibility – Functional and artwork revisions should match the existing system documentation. Mixing incompatible revisions can cause communication or diagnostic issues.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified DS200CTBAG1ADD?
As a legacy Mark V board, availability depends on surplus stock. Typical lead time after verification is 3–12 business days plus standard air freight.
What is the function of the DS200CTBAG1ADD?
It is the Analog Termination Module (CTBA) that lands 4–20 mA signals, shaft signals, and provides COREBUS/IONET connections in a Mark V system.
Where is it typically installed?
In the core of the Mark V Speedtronic control panel.
What system is it used with?
GE Mark V Speedtronic turbine control systems (gas and steam turbines).
Is it still in production?
No. Mark V boards are discontinued by GE and are now supplied through surplus and repair channels.
What are the key connectors?
JAI and JAJ (COREBUS), JAA (4–20 mA outputs), and 8PL (IONET to STCA).
What should be confirmed before ordering a replacement?
Exact part number including the full revision suffix (G1ADD), core location, and compatibility with the existing Mark V configuration.
