IS220PAOCH1BD GE Module Parts Mark VIe PAOC Analog Output Module
The GE IS220PAOCH1BD is a PAOC (Analog Output) I/O Pack designed for the GE Mark VIe Speedtronic turbine control system. It provides the electrical interface between the I/O Ethernet network and compatible analog output terminal boards.
The module converts digital control commands from the Mark VIe controller into analog output signals for controlling field devices such as turbine fuel valves, inlet guide vanes, actuators, and other industrial equipment.
The PAOC I/O Pack supports up to eight simplex analog current outputs, making it suitable for applications requiring accurate and reliable analog signal control.
It is commonly used in gas turbine control, steam turbine systems, power generation, and industrial process automation.
