Product Description

The GE General Electric IS200ACLAH1A functions as an Application Control Layer Module within the EX2100 Excitation Control System. Broadly, this PCB aids in outer loop functions and network communications for the control system. The IS200ACLAH1A is also responsible for enabling ethernet communcations as needed for the LCI, Turbine Control, and associated Human Machine Interface (HMI). Among other control functions within the IS200ACLAH1A capacity, are the following:

• Power Factor Regulation/VAR
• PSS or Power System Stabilizer
• Under Excitation Limit Control (UEL)
• Automatic Voltage Regulation (AVR)

The IS200ACLAH1A is commonly abbreviated to ACLA it relates to the similar nature of the former PCB with perhaps small revison differences. The ACLA Board is a double-slot module and is located next to the DSPX module in the rack. If Qty 2 ACLA Cards exist in the same system, there is a built in redundancy in control that is gained by this structure. The IS200ACLAH1A will generally be seen as the part number printed on the PCB while often there will be another number present (IS215ACLAH1A) that refers to the totality of the module with faceplate and attached firmware.
