ABB RF523 Subrack 18SU Including Backplane

Description

ABB RF523 Subrack 18SU Including Backplane is a rack-mountable industrial subrack system, with the closely matched ABB RF522 3BSE000743R1 serving as a comparable reference for technical specifications. The 18SU designation refers to its standardized size specification. The unit includes an integrated backplane, and its core components consist of the subrack body, backplane, and pre-configured mounting holes. Key functions include providing rigid support and secure fixation for electronic equipment, enabling interconnection between installed devices via the backplane’s connection interfaces, and offering physical protection against external environmental interference.

Constructed with high-strength metal materials, it delivers excellent mechanical stability and electrical conductivity. It features a modular design for flexible integration with compatible automation equipment, easy installation with multiple mounting options to suit diverse environments, and broad compatibility with various electronic modules such as digital input/output, analog input/output, and control units. Technical specifications include defined load-bearing capacity, specific mounting hole dimensions, quantity, and distribution, plus physical dimensions of 540mm depth, 297mm height, 441mm width, and a net weight of 19.3 kg. Ideal for building control cabinets and switchboards, it is widely applied in industrial automation control systems, power systems, building automation systems, robot systems, and scenarios like factory automation, building automation, data centers, and transportation.
