1. Product Overview
IS200ACLEH1A is an Application Control Layer Module manufactured by General Electric (GE), which is specially designed for the EX2100 excitation control system. As a product of the IS200 series, it is an integral part of the Mark VI series. The ACLE board of the IS200 version serves as the basic module before the upgrade to the higher-level IS215.
This module is a microprocessor-based main controller, designed to perform multiple tasks simultaneously through an Ethernet communication network. In terms of hardware identification, IS200 represents the assembly version of theMark VI series, and ACLE is the abbreviation for Application Control Layer function.
