GE IS220PTURH1B IS220PTURH1BF stores energy using two electrolytic capacitors. Together, they provide 220 µF at 35V rating for output hold-up. This energy storage maintains digital outputs during 25 millisecond power interruptions. Therefore, the I/O pack prevents false switching in turbine control environments.
Design and Integration
Both the GE IS220PTURH1B and IS220PTURH1BF versions share identical I/O circuitry. These I/O packs use six-layer PCB construction with isolated I/O banks for noise immunity. Consequently, the GE IS220PTURH1B IS220PTURH1BF operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The I/O pack draws 300 mA typical current from the 24V DC supply. Each analog input includes software selectable filtering. We recommend using shielded cables for all analog field connections.
Practical Application
This turbine I/O pack connects field sensors and actuators to a Mark VIe controller. It reads speed probes, thermocouples, and pressure transmitters continuously. The GE IS220PTURH1B IS220PTURH1BF then sends output commands to servo valves and trip solenoids. Therefore, it serves as a compact I/O interface for GE Mark VIe turbine control systems.
