Description
🔹 Product Description
The GE General Electric IS200TFBAH1A, associated with assembly designation IS200TFBAH1ACB, is a TFBA Temperature Feedback Board designed for the GE Mark VI Speedtronic turbine control system. GE Mark VI systems were developed for monitoring and control of gas and steam turbine processes. Technical references identify the TFBA functional acronym as Temperature Feedback Board Assembly.
The board uses conformal coating for PCB protection and incorporates a transformer, integrated circuits, jumper pins, a large capacitor, and other signal-processing circuitry. The J3 jumper group provides configuration capability, while the board’s electronic circuitry supports temperature-feedback functions within the compatible Mark VI control architecture.

🔹 Common Questions & Answers
Q: What is the GE IS200TFBAH1A?
A: It is a GE Mark VI TFBA Temperature Feedback Board Assembly used in compatible turbine control applications.
Q: What does TFBA stand for?
A: TFBA is the functional acronym for Temperature Feedback Board Assembly.
Q: What GE system is the IS200TFBAH1A designed for?
A: It was manufactured for the GE Mark VI Speedtronic Turbine Control System.
Q: What is the purpose of the board?
A: The board provides temperature-feedback circuitry for compatible GE turbine control hardware, supporting temperature monitoring within the Mark VI architecture.
Q: Does the board have configuration jumpers?
A: Yes. The IS200TFBAH1A includes a jumper-pin group identified as J3. Jumper positions should be matched to the original system configuration before installation.
Q: Is the PCB conformally coated?
A: Yes. Technical documentation identifies conformal coating across the PCB.
Q: Is IS200TFBAH1A interchangeable with another Mark VI temperature board?
A: Replacement should not be assumed to be plug-and-play. Verify the complete part number, assembly/revision code, connectors, jumper configuration, and system application before substitution.
Q: Is the IS200TFBAH1A discontinued?
A: Current parts listings identify it as discontinued by the manufacturer, so replacement units are commonly sourced through legacy spare-parts channels.
Q: What should be checked before installation?
A: Verify the full part number, inspect the PCB and connectors, compare J3 jumper positions with the original board, check for physical or component damage, and follow the applicable GE Mark VI maintenance procedure.
