GE IS200VTURH2B IS200VTURH2BAC stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for relay hold-up. Consequently, the board maintains trip outputs during 25 millisecond power interruptions. Therefore, safety trips remain active through brief voltage dips.
Design and Integration
Both the GE IS200VTURH2B and IS200VTURH2BAC versions share identical safety circuit topology. These boards use four-layer PCB construction with force-guided relay contacts for safety compliance. Consequently, the GE IS200VTURH2B IS200VTURH2BAC operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 150 mA typical current from the 24V DC supply. Each safety relay includes positive-guided contacts for diagnostic coverage. We recommend using 18 AWG wire for all trip output connections.
Practical Application
This turbine protection circuit board initiates turbine shutdown upon detecting critical faults. It receives trip commands from overspeed and vibration protection systems. The GE IS200VTURH2B IS200VTURH2BAC then opens safety relays to de-energize trip solenoids. Therefore, it provides reliable emergency protection for GE turbine control systems.
