GE IS200AEPCH1ABC Mark VI Speedtronic AEPC Auxiliary Control Processor Board

Description

GE IS200AEPCH1ABC Mark VI Speedtronic AEPC Auxiliary Control Processor Board

Product Description

The IS200AEPCH1ABC is an AEPC auxiliary processor PCB card designed for GE Speedtronic Mark VI turbine control systems, also compatible with EX2100 excitation control platform. This plug-in auxiliary board handles high-speed signal timing, auxiliary logic processing and inter-board communication between the main controller and I/O packs. It processes analog and digital field signals, manages local timing sequences and transfers critical measurement & status data across the rack backplane. The PCB is conformal coated for protection against humidity, dust and airborne contaminants in power plant cabinets. It supports simplex and TMR triple modular redundant architectures, playing a vital supporting role for gas/steam turbine closed-loop control, excitation regulation and machine protection functions.
