Description
The GE IS200VTURH1B is a VME Primary Turbine Protection Board designed for the GE Mark VI Speedtronic Turbine Control System. The VTUR board is a critical protection module responsible for turbine speed measurement, primary overspeed trip generation, and turbine safety monitoring functions.
The IS200VTURH1B receives speed signals from turbine pickup devices, processes shaft speed information, and controls the primary overspeed trip relay circuits through compatible TRPx terminal boards. It also supports shaft voltage/current monitoring and flame detector interfaces for applicable gas turbine configurations.
This VME-based board is widely used in GE Mark VI turbine control cabinets for gas turbines, steam turbines, and generator control systems where reliable turbine protection and emergency shutdown functions are required. The board works together with components such as TTUR and TRPG/TRPL terminal boards.

🔹 Common Questions & Answers
Q: What is the main function of IS200VTURH1B?
A: The IS200VTURH1B is a GE Mark VI turbine protection board that measures turbine speed and provides primary overspeed trip control functions.
Q: Which GE systems use IS200VTURH1B?
A: It is mainly used in GE Mark VI Speedtronic turbine control systems and VME-based turbine protection racks.
Q: Is IS200VTURH1B compatible with Mark VIe systems?
A: No. The IS200VTURH1B is designed for the GE Mark VI VME architecture and should not be treated as a direct Mark VIe replacement.
Q: Which terminal boards work with this VTUR board?
A: The board is commonly associated with TTUR and TRPx terminal board families, including TRPG for gas turbine applications and TRPL for certain steam turbine applications.
Q: What should be checked before replacement?
A: Confirm the complete part number, hardware revision, VME rack configuration, TTUR/TRPG/TRPL terminal board compatibility, wiring connections, and turbine control parameters before installation.
Q: What faults may appear related to VTUR?
A: Speed signal loss, overspeed trip alarms, communication faults, or protection errors may involve the VTUR board, but field sensors, terminal boards, wiring, and power supplies should also be checked.
