IS215ACLAH1A - ACLA Application Control Layer Module | GE EX2100 | B7B

IS215ACLAH1A is a General Electric ACLA Application Control Layer Module for GE EX2100 excitation control systems. In the EX2100 control module, the ACLA works alongside the DSPX controller and other control rack boards to support Ethernet communications and outer-loop control functions used in generator field control applications.

The GEH-6632G EX2100 user guide describes the ACLA as a double-slot module located next to DSPX, providing Ethernet communications with the turbine control, LS2100, and HMI, while running outer-loop control functions including Automatic Voltage Regulator (AVR), Power System Stabilizer (PSS), Under Excitation Limit control (UEL), and VAR/power factor regulator (VAR/PF) functions; the source specifically states that ACLA cannot be used in place of ACLE. For maintenance, repair, and spare-part planning, IS215ACLAH1A is an important replacement control module when supporting EX2100 excitation control cabinets, redundant or simplex control architectures, and turbine-generator excitation system reliability.

Control system parts are provided by GTC Control Solutions, Inc., a wholly owned subsidiary of B7B. Parts are offered in unused, repaired, or remanufactured condition, subject to availability. Each repaired or remanufactured component undergoes functional testing in energized panels, with test reporting and warranty support provided for repair and lifecycle-extension programs.
