GE IS220PTURH1A stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for relay hold-up. Consequently, the pack maintains trip outputs during 25 millisecond power interruptions. Therefore, safety trips remain active through brief voltage dips.
Design and Integration
This turbine protection pack uses four-layer PCB construction with force-guided relay contacts for safety compliance. Consequently, the GE IS220PTURH1A operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The pack 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 primary protection pack initiates turbine shutdown upon detecting critical faults. It receives trip commands from overspeed and vibration protection systems. The GE IS220PTURH1A then opens safety relays to de-energize trip solenoids. Therefore, it provides reliable emergency protection for GE turbine control systems.
