GE IS220PAICH1A stores energy using one electrolytic capacitor. This capacitor provides 100 µF at 35V rating for output hold-up. Consequently, the module maintains analog outputs during 20 millisecond power interruptions. Therefore, actuators remain stable through brief voltage dips.
Design and Integration
This analog I/O module uses six-layer PCB construction with separate analog and digital grounds. Consequently, the GE IS220PAICH1A operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M3 screws for the four mounting holes. The module draws 250 mA typical current from the 24V DC supply. Each output channel can drive loads up to 20 mA maximum. We recommend using shielded cables for all analog field connections.
Practical Application
This analog I/O module connects field sensors and actuators to a Mark VIe controller. It reads temperature, pressure, and flow signals from turbine systems. The GE IS220PAICH1A then sends control outputs to valves and positioners. Therefore, it serves as a compact analog interface for GE turbine control systems.
