GE IS220PAICH1A/B

Product Name: Analog I/O Pack

Product Description:

The GE IS220PAICH1A/B is an Analog Input/Output (I/O) Pack designed for use with GE’s Mark VI and Mark VIe series control systems, primarily for turbine control. It provides the interface between I/O Ethernet networks and analog input terminal boards. The module handles analog input signals from field devices, converting them into digital data for the control system, and also provides analog output signals to control actuators and other analog devices. The “-A” and “-B” suffixes indicate different hardware revisions with potentially varying specifications and compatibility.
