GE IS200TSVOH1BCC TSVO Servo Terminal Board

Product Description

IS200TSVOH1BCC is a TSVO servo terminal board for GE Mark VI / Mark VIe Speedtronic turbine control system. It is conformal coated for harsh cabinet environments, equipped with two independent servo channels to interface electro-hydraulic servo valves and LVDT position feedback sensors. This board supports simplex and TMR triple modular redundant configurations, designed for precise fuel and steam valve control on gas and steam turbines.

Product Functions

• Provide termination and signal conditioning for 2 servo control channels
• Supply LVDT excitation signal and receive valve position feedback
• Drive electro-hydraulic servo valves for accurate valve positioning
• Support 1 to 3 LVDT/LVDR sensors per channel for position redundancy
• Filter high-speed control signals and suppress field EMI interference
• Work with main I/O pack in TMR architecture for fault-tolerant turbine control

Applications

• Gas turbine and steam turbine governing valve control in power plants
• Electro-hydraulic actuator interface for turbomachinery control racks
• Oil & gas, petrochemical critical turbine and compressor control systems
• Spare replacement and retrofit for legacy Mark VI / Mark VIe cabinets
• EX2100 excitation and turbine governor integrated control systems
