Steam Turbine Excitation System CPU board PCA-6743VE

Short Description:

Steam Turbine Excitation System CPU board PCA-6743VE is used in the GES3320 excitation system. GES3320 is a microcomputer based control system. The automatic voltage regulator consists of two industrial computes employing open ISA bus, and some peripheral equipment, for instance HMI, communication, measuring, and so on.
Brand: YOYIK

Product Detail

Each computer is composed of Steam Turbine Excitation System CPU board PCA-6743VE, A/D converter board, binary I/O board, serial communication board, and pulse forming board.

Based on the two computers, the regulator forms a dual-channel system in the main. That means two same sets of measuring; input, computing, and output are included. The cooperating between the two sets will be descripted in the operation manual
