GE IS200TTURH1CEC Turbine Terminal Board (TTURH)

Product Description: The IS200TTURH1CEC is a GE Speedtronic Mark VI / Mark VIe turbine termination board, matched with PTUR protection I/O pack. It is a conformal coated version for corrosive cabinet environments. It collects and conditions MPU speed signals, generator voltage PT signals, vibration probe signals, analog 4-20mA and hardwired trip discrete signals, and transfers these signals to the PTUR pack for generator synchronizing, overspeed protection and turbine trip logic calculation. The conformal coating protects PCB circuits from humidity, salt fog and dust in offshore or high-humidity power plant cabinets.

Features:

• Designed for GE Mark VI and Mark VIe turbine control, supports simplex, duplex and TMR triple redundant configurations
• Full conformal coated PCB (CEC suffix), suitable for corrosive, humid and offshore environments
• Integrated signal transformers, filtering and surge suppression for PT voltage and MPU pickup inputs
• Screw terminal blocks and D-sub connectors for field instrument wiring
• Mainly paired with IS220PTURH1A protection pack for synchronization and overspeed protection
• Eurocard plug-in design, installed on Mark VI backplane, hot-swap capable
• Onboard LED indicators for signal status and channel fault diagnosis

Applications:

• Gas turbine and steam turbine Mark VI / Mark VIe synchronization & overspeed protection cabinet
• Offshore platform turbine control panel with high humidity and salt mist
• EX2100 generator excitation system voltage signal acquisition
• Oil & gas compressor turbine safety protection system
• Legacy Mark VI system spare replacement and offshore retrofit project

FAQ:

Q: What is the difference between IS200TTURH1CEC and standard IS200TTURH1C?
A: IS200TTURH1CEC has conformal coating; the standard IS200TTURH1C is uncoated. They are not direct drop-in replacement for corrosive cabinets.

Q: Can it work without PTUR pack?
A: No, it is only the termination and signal conditioning base board, must work together with PTUR I/O pack.

Q: Can it be used on Mark VIeS safety system?
A: It can be applied on Mark VIe, but firmware and ControlST version must be verified before replacement.

Q: Is IS200TTURH1CEC still in production?
A: Mark VI series turbine hardware is obsolete. Available supply is NOS surplus or fully tested refurbished boards.
