- Long Service Life: High-quality materials and manufacturing ensure reliable operation for 10+ years in continuous duty
Application Scenarios
Process Control Redundancy: In chemical processing plants, the PMKHRMBRC3000A 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.
Power Generation Systems: 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 Upstream: Offshore platforms use PMKHRMBRC3000A cables in safety-instrumented systems (SIS) controlling emergency shutdown valves. The cable's temperature rating supports installation in both climate-controlled rooms and exposed equipment enclosures.
Installation & Configuration
The PMKHRMBRC3000A requires no special tools or calibration. Simply connect one end to the primary BRC module's redundancy port and the opposite end to the backup module. The system automatically detects the connection and enables redundancy mode. Ensure proper cable routing to avoid sharp bends (minimum radius: 50mm) and secure with appropriate cable management hardware.
Common Technical Questions
Q: Can this cable be used with BRC100 or BRC200 modules?
A: No, the PMKHRMBRC3000A is specifically designed for BRC300 and BRC400 series controllers. Earlier BRC generations use different connector pinouts.
Q: What is the maximum recommended cable length for redundancy connections?
A: ABB specifies 3 meters as the optimal length. Longer runs may introduce signal degradation. For installations requiring greater separation, consult ABB engineering for fiber-optic redundancy solutions.
Q: Does the cable support hot-swapping?
A: While the cable itself is passive, hot-swapping is not recommended. Always follow proper shutdown procedures outlined in the Infi 90 system manual before disconnecting redundancy cables.
Q: How do I verify the cable is functioning correctly?
A: The BRC controller's diagnostic LEDs will indicate redundancy status. Green indicates healthy redundancy link; amber suggests communication issues. Use the Infi 90 engineering workstation to view detailed redundancy diagnostics.
Warranty & Support
All PMKHRMBRC3000A cables include a comprehensive 12-month manufacturer warranty covering defects in materials and workmanship. Extended warranty options and technical support packages are available through authorized ABB distributors.
