GE IS200VTURH1B
-
Product Identity: A critical turbine protection card forming part of the Speedtronic™ Mark VI control architecture.
-
Functional Overview: The VTUR acts as the primary guardian for rotating equipment. It monitors shaft rotational speed via magnetic pickups, manages overspeed detection with hardware-voted logic, and supervises flame detection systems. Upon detecting hazardous conditions, it triggers emergency trip circuits to halt fuel flow instantaneously.

Technical Specifications:
-
Speed Range: Capable of measuring speeds up to 10,000 RPM with high resolution.
-
Isolation: 2500V AC dielectric isolation between field wiring and internal logic to prevent ground loops.
-
Voting Logic: Supports Triple Modular Redundant (TMR) configurations for enhanced safety integrity level (SIL).
-
Indicators: Front-panel LED matrix displaying speed values, trip status, and diagnostic codes.
-
-
Material Composition: Utilizes high-temperature laminate substrates and gold-plated edge connectors to ensure long-term reliability under thermal cycling.
-
Application Context: Essential in combined-cycle power plants, oil and gas refineries, and marine propulsion systems where turbine overspeed could result in loss of life or asset destruction.
-
Safety Notes: Calibration must only be performed by certified personnel using approved GE software tools. Ensure backup batteries are checked regularly if applicable to the rack configuration.
