The GE IS215ACLEH1CA is a microprocessor-based Application Control Layer Module, a key
component in GE’s Innovation Series drives and EX2100 excitation
control systems. Designed as a master controller, it operates over
Ethernet and ISBus networks, fitting into two half-slots in
standard drive racks or EX2100 exciter backplanes. Housed in
control cabinets, it orchestrates critical functions like
communication, data processing, and system coordination for
industrial drives and turbine excitation systems.
Equipped with a 128 KB L2 cache, 8 MB DRAM, and 4 MB flash BIOS, it
integrates a CPU, PCI controller, and interfaces for seamless data
exchange. Its functional revision “C” denotes updates, ensuring
compatibility with modern systems while lacking backward
compatibility with older ACLA models.
Features:
Centralized Control: Acts as a master controller, managing communication over Ethernet
and ISBus to coordinate drives, sensors, and subsystems.
Robust Hardware: Includes a CPU, PCI controller, 128 KB L2 cache, and 8 MB DRAM for
efficient data processing; 4 MB flash BIOS supports firmware
storage and booting.
Flexible Mounting: Fits two half-slots in Innovation Series drive racks or EX2100
exciter racks, adapting to diverse industrial setups.
Software Capabilities: BIOS initializes hardware, directs boot sequences via COM1, and
enables flash disk support; GE’s Control Systems Toolbox configures
runtime actions, loads Pcode, and upgrades firmware over Ethernet.
Industrial Reliability: Designed for harsh environments, with secure backplane
connectivity and robust components ensuring stable operation in
drives and excitation systems.
