GE Fanuc IS200AEADH1A Analog Input Terminal Board

In stock

Product Overview:
The GE Fanuc IS200AEADH1A is a high-density analog input termination board designed for the Mark VIe and Mark VI Series turbine control systems. This module serves as the critical interface between field analog sensors (such as RTDs, thermocouples, and milliamp/voltage transmitters) and the Mark VI controller’s internal processing units. It provides signal conditioning, isolation, and analog-to-digital conversion for up to 16 channels of analog input data, making it essential for monitoring critical process variables like temperature, pressure, flow, and vibration in power generation and industrial applications.
