GE IS220PAOCH1A Analog Output Module

GE IS220PAOCH1A is a process analog output module for GE Mark VIe distributed turbine control system. It converts digital control commands from the main controller into standard analog signals to drive field control valves, actuators and regulating devices, serving as the analog control output interface for turbine control loops.

This module supports multiple analog output signal types including 4-20mA current and 0-10V voltage, with high-precision D/A conversion and channel isolation. It communicates with the controller via Ethernet, supporting redundant network configuration. It is widely used as spare replacement parts for gas and steam turbine control cabinet maintenance and retrofit in power plants.
