General Electric IS200AEADH4ADA Input Terminal Board

The GE IS200AEADH4ADA is a specialized Analog Electrostatic Discharge and Attenuation Terminal Board (AEAD) designed for use within the GE Mark VI and Mark VIe control systems. It functions as an interface between field-mounted analog sensors and the core control electronics, facilitating clean, safe, and reliable signal transmission. The AEADH4ADA version belongs to a refined series that ensures robust analog signal integrity by filtering noise and safeguarding input channels against electrostatic discharge (ESD) and transient voltage spikes.

As an input terminal board, the IS200AEADH4ADA serves as the first point of contact for incoming analog signals, conditioning them before they’re routed to analog input modules. The module’s rugged design and conformity to GE’s strict quality standards make it ideal for demanding industrial environments such as power plants, oil & gas refineries, and heavy manufacturing.
