The GE IS215ACLEH1C is an Application Control Layer (ACL) Module used in GE Mark VI turbine control and EX2100 excitation systems. It serves as a high-level control processor board, responsible for executing application logic, managing communication between subsystems, and coordinating turbine or drive control strategies.
In industrial automation, this module acts as a software-driven control layer, sitting above I/O and signal conditioning boards to ensure precise execution of control algorithms in real time.
