ABB S-123H 3BHB030479R0512 Phase Module

Product Description

ABB S-123H (3BHB030479R0512) is a high-performance industrial control module developed for ABB generator excitation and power drive control systems. As a key signal processing unit within

 the control cabinet, it completes analog and digital signal acquisition, signal conversion, real-time data calculation and communication transmission tasks. The module adopts industrial-grade 

electronic components and optimized circuit design, adapting to the harsh operating environment of power stations with large temperature fluctuation and strong electromagnetic interference. 

It can continuously work for a long time without failure, mainly used for maintenance and spare parts replacement of excitation control cabinets in thermal power, hydropower and other power 

generation industries, ensuring the whole excitation system runs steadily and the generator keeps normal grid-connected operation.
