Functional Description
The IS200ACLEH1BAA processes control tasks within the EX2100 platform and exchanges data with other control components. Its CPU executes control software, while the PCI controller supports communication between internal hardware components. The cache memory provides fast access to frequently used instructions and data during processor operations.
Communication and Hardware Interfaces
The module supports Ethernet communication and an ISBus interface for exchanging information with connected system components. COM1 and COM2 provide additional serial communication channels. The exact protocols, transmission rates, and port configuration depend on the applicable system documentation.
Installation and Backplane Connection
The ACL module occupies two half-slots in a compatible Innovation Series drive or EX2100 exciter board rack. In drive applications, it connects to the Control Assembly Backplane Board (CABP) through a P1 connector with four rows and 128 pins. In EX2100 exciter applications, the module mounts on the Exciter Backplane (EBKP).
Before replacement, verify the complete part number, rack configuration, and backplane connection. The physical fit alone does not confirm electrical or functional compatibility with a particular control system.
