Application Scenarios

In a thermal power plant’s boiler control system, the existing Bailey Infi 90 DCS relied on a pair of BRC400​ controllers configured for redundancy. During a scheduled maintenance window, the engineering team discovered that the original redundancy cable had become brittle due to prolonged exposure to high ambient temperatures. They replaced it with the ABB PMKHRMBRC3000A. The new cable’s robust shielding effectively minimized EMI from nearby high-voltage switchgear, while its precise 4 cm length allowed for a clean and strain-free connection within the tight confines of the controller rack. During a subsequent simulated fault test, the standby BRC400 controller assumed control within milliseconds without process interruption, validating the cable’s critical role in maintaining high availability.
