GE IS200TBAIH1CFD TBAI Analog Input Terminal Board

Product Description: The IS200TBAIH1CFD is a GE Speedtronic Mark VI analog input termination board (TBAI). It serves as the field wiring interface for analog transmitters, routing 4-20mA and ±voltage analog signals from process sensors to the VAIX / VAIC analog I/O pack. This variant CFD indicates specific hardware revision and conformal coating treatment, designed for humid, corrosive cabinet environments. It supports simplex, duplex and TMR triple redundant turbine control architectures for gas and steam turbine monitoring and closed-loop control.

Features:

• Mark VI dedicated analog input terminal board, paired with VAIX or VAIC analog processor pack
• 10 analog input channels plus 2 analog output channels; compatible with 4-20mA, ±5V, ±10V signals
• Supports 2-wire, 3-wire and 4-wire transmitter wiring configurations
• Three 37-pin D-sub connectors for TMR R/S/T channel signal distribution
• Built-in surge suppression and EMC filtering to reduce noise interference in power plant cabinets
• CFD suffix: conformal coated PCB for anti-humidity, anti-salt mist protection
• Eurocard plug-in form factor for Mark VI rack backplane installation
• Barrier screw terminal blocks for convenient field wiring and maintenance

Applications:

• Gas turbine and steam turbine Mark VI analog signal monitoring cabinet
• Power plant bearing vibration, pressure, flow and temperature analog signal collection
• EX2100 generator excitation system analog measurement loop termination
• Oil & gas compressor turbine control cabinet spare replacement
• Offshore platform turbine control system with high humidity and salt fog environment

FAQ:

Q: What does TBAI stand for?
A: TBAI = Terminal Board Analog Input, the analog signal termination base board for Mark VI analog packs.

Q: What is the difference between IS200TBAIH1CFD and IS200TBAIH1C?
A: CFD is a coated revision. The base circuit function is the same, but conformal coating makes it suitable for corrosive environments; uncoated versions cannot directly replace it in offshore applications.

Q: Can it work on Mark VIe racks?
A: No, it belongs to classic Mark VI platform and is not compatible with Mark VIe IONet architecture and backplane.

Q: Is IS200TBAIH1CFD still in production?
A: Mark VI series turbine hardware is obsolete. Available supply is NOS surplus or fully tested refurbished boards.
