GE IS220STAIH2ACB Analog Input Module

Product Description

The IS220STAIH2ACB is a high-performance analog input pack designed specifically for the GE Mark VIe control system architecture. This module serves as a critical interface for distributed control, converting field-level analog signals into digital data for high-speed processing. It is engineered to provide the precision and reliability required for steam and gas turbine control, as well as general power generation automation.

As part of the Mark VIe "S" series, the IS220STAIH2ACB is built for decentralized I/O configurations. It features a ruggedized enclosure capable of withstanding extreme temperature fluctuations and electromagnetic interference. The module integrates a sophisticated 16-bit analog-to-digital converter (ADC) to ensure that even the most minute process variations are captured and reported back to the controller via redundant Ethernet IONets.
