Product Overview
The ABB PMKHRMBRC3000A (also referenced as BRC3000A) is a factory-terminated, industrial-grade redundancy link cable assembly engineered exclusively for ABB's Bailey INFI 90 and Symphony Plus (Harmony Rack) distributed control systems (DCS). This critical connectivity component establishes high-reliability redundant communication links between bridge controllers and communication modules, enabling fault-tolerant control architectures with seamless failover protection.
In large-scale industrial DCS installations, the PMKHRMBRC3000A is the physical backbone of redundant communication networks, directly determining system stability and continuous operation capability. When deployed in dual-controller configurations, this cable maintains continuous communication pathways and automatically reroutes data if the primary link fails, eliminating single points of failure.

Compatible Modules
This cable is purpose-built to connect the following ABB Bailey controller and communication modules in redundant pairs:
BRC300, BRC400, BRC410 – Bridge Controllers
NPM22 – Network Process Modules
RIO22 – Remote I/O Modules
HPG800 – High-Performance Gateway Modules
Core Functions & Features
Dual Redundant Link, Zero-Downtime Protection
The PMKHRMBRC3000A features built-in dual redundant data transmission paths. When the primary link experiences a fault, the system automatically and seamlessly switches to the backup link, ensuring critical DCS communication never fails and production continuity is maintained.
Industrial-Grade Shielding
Multi-layer shielded cable with proprietary ABB BRC interface connectors effectively isolates control signals from electromagnetic interference generated by motors, variable frequency drives, and other industrial equipment. Data transmission achieves zero packet loss and zero errors.
Wide Temperature & Harsh Environment Tolerance
Adapts to -40°C to +85°C temperature extremes. Constructed with wear-resistant, corrosion-resistant, and anti-aging materials, it operates reliably in outdoor, high-temperature, high-humidity, and other severe conditions.
Original Factory Compatibility
100% compatible with ABB INFI 90, Symphony DCS, and BRC bridge controllers. Plug-and-play installation requires no additional configuration and enables rapid replacement of faulty links.
Hot-Swappable Architecture
Modular design supports quick plug-and-play operation. Cable replacement and inspection can be performed online without system shutdown, significantly improving production efficiency.
Application Scenarios
Power Generation – Utility-scale power plants deploy this cable in turbine control systems where redundant controllers monitor vibration, temperature, and speed parameters. The cable's EMI shielding is essential in high-voltage switchyard environments.
Oil & Gas – Offshore platforms and refineries use PMKHRMBRC3000A cables in safety-instrumented systems (SIS) controlling emergency shutdown valves. The temperature rating supports installation in both climate-controlled rooms and exposed equipment enclosures.
Chemical & Petrochemical – In chemical processing plants, the cable connects dual BRC controllers managing critical reactor temperature and pressure loops. When the primary controller experiences a fault, the cable facilitates instantaneous switchover to the backup unit, preventing costly batch losses.
Other Industries – Steel mills, paper manufacturing, pharmaceutical production, water treatment, and any industrial facility requiring high-availability DCS control with redundant architecture.
Why Choose PMKHRMBRC3000A
Guaranteed compatibility with legacy and current ABB DCS platforms
Factory-tested for signal integrity and mechanical durability
Reduces mean time to repair (MTTR) through plug-and-play installation
Supports high-availability architectures with zero single points of failure
Long service life design – 10+ years of reliable operation in continuous duty
