GE IS220PAICH2AA
Product Name: GE Mark VIe Analog Input/Output Module with HART Support
Introduction: The IS220PAICH2A (listed as IS220PAICH2AA) is a high-performance analog I/O module (Analog I/O Pack) widely used in GE Mark VIe gas turbine, steam turbine, and industrial process control applications. It is an intelligent front-end device with active communication capabilities, typically installed in a VME rack and directly plugged into a terminal board via a DC-37-pin connector, serving as the core link between field sensors/actuators and the digital control system.
