ABB PMKHRMBRC1000A Redundant BRC Cable Assembly

ABB PMKHRMBRC1000A Redundant BRC Cable Assembly

Basic Information

Product Model:PMKHRMBRC1000A.

Product Name：Redundant BRC Cable Assembly, i.e. Redundant BRC Cable Assembly, is mainly used to provide reliable and redundant communication connections for related systems, to ensure that the system can still maintain normal communication in the event of failure of some components.

Areas of application

It is mainly used in ABB Bailey Infi 90 system to provide redundant communication between BRC and other devices in the system, in order to meet the strict requirements of system reliability and stability in the process of industrial automation, which is widely used in automation control system of chemical, electric power, metallurgy, petroleum and other industries.

Features and Advantages

Redundant design: as a redundant cable assembly, it has two or more independent communication lines, when one of the lines fails, the system can automatically switch to other normal lines, thus ensuring the continuity of communication, effectively avoiding system downtime due to a single point of failure, and greatly improving the reliability and usability of the entire system, which is particularly important for the key aspects of industrial production that are not allowed to be interrupted.

High-quality materials and manufacturing process: the use of high-quality conductive materials and insulating materials to ensure that the cable has good electrical conductivity, low attenuation and high interference resistance, able to transmit signals stably in the complex industrial electromagnetic environment. At the same time, the exquisite manufacturing process ensures the consistency and reliability of the cable, so that it can operate stably for a long time, reducing maintenance costs and replacement frequency.

Strong compatibility: good compatibility with a variety of devices and modules in the ABB Bailey Infi 90 system, such as BRC300, BRC400 and other related controllers and modules, can be seamlessly integrated into the existing system, without the need to carry out complex configuration and debugging, to facilitate the user to carry out system expansion and upgrading.

Adaptation to harsh environments: Taking into account the harsh environmental conditions of industrial sites, such as high temperature, humidity, dust, vibration, etc., the cable assembly has a strong environmental adaptability. Its external sheath has good corrosion resistance, abrasion resistance and weather resistance, can effectively protect the internal cable core from external factors, to ensure that in a variety of harsh working conditions can work normally.

Easy to install and maintain: reasonable design, compact structure, easy to install and wiring in the system. At the same time, its standardised interfaces and clear markings make it easy for maintenance personnel to carry out overhaul, troubleshooting and replacement operations, which reduces the difficulty and workload of maintenance and improves the maintainability of the system.

• 16 MB synchronous dynamic RAM,   8 MB EPROM

The AC 800F optionally provides several levels  of redundancy: 

• device redundancy with 2 AC 800F  

• power supply redundancy (24 V DC)  

• Ethernet communication redundancy   (standard)  

• Cable redundancy for Profibus DP,   requires external equipment (RLM01)

AC 800F Controller Redundancy

Controller redundancy can be achieved by installing two  AC 800F. To ensure quick and smooth takeover by the secondary AC 800F in case the primary AC 800F fails, a dedicated  redundancy communications link through the second Ethernet  module makes sure that both AC 800F are always synchronized. All inputs and outputs are designed to support redundant  operation.
