The HONEYWELL 8C-PCNT02 is a high-availability redundant control processor for Honeywell’s ControlEdge™ PLC platform, engineered for critical process safety and control applications with SIL 3 certification. This dual-module system ensures continuous operation through seamless failover during hardware faults or cyber incidents.
Application Scenarios
During a pipeline rupture event at a Canadian oil sands facility, the 8C-PCNT02 maintained control of emergency shutdown valves while the primary processor recovered from a voltage spike. Its <100ns switchover prevented hydrocarbon release – avoiding $18M environmental penalties and demonstrating fault tolerance where traditional PLCs would fail.
