GE IS200VPROH1B IS200VPROH1BEF stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for relay hold-up. This energy storage maintains trip outputs during 25 millisecond power interruptions. Therefore, safety trips remain active through brief voltage dips.
Design and Integration
Both the GE IS200VPROH1B and IS200VPROH1BEF versions share identical safety I/O circuitry. These boards use six-layer PCB construction with force-guided relay contacts for safety compliance. Consequently, the GE IS200VPROH1B IS200VPROH1BEF operates reliably from -15°C to +60°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The board draws 250 mA typical current from the 24V DC supply. Each safety relay includes positive-guided contacts for diagnostic coverage. We recommend using separate cable trays for input and output wiring.
Practical Application
This turbine emergency trip I/O board monitors critical safety inputs and initiates shutdown. It reads overspeed, vibration, and flame detector signals continuously. The GE IS200VPROH1B IS200VPROH1BEF then opens safety relays to de-energize trip solenoids. Therefore, it provides reliable emergency protection for GE turbine control systems.
