Functional Characteristics
- TMR ArchitectureTriple redundant fault-tolerant design with three independent processing circuits running identical logic synchronously. Hardware voting on I/O signals ensures single-point failures do not affect operation. Failover ≤5s, eliminating safety shutdowns from single faults.
- Real-Time Processing & SOEHigh-speed execution of safety control programs with Sequence of Events (SOE) recording, time resolution ≤40ms, enabling accurate fault and operation sequence logging for accident analysis.
- Online DiagnosticsBuilt-in self-diagnosis every 60 seconds, monitoring CPU, memory, bus and I/O status. Automatic fault alarm and localization, supporting online module maintenance without field wiring interruption.
- System ScalabilitySupports up to 118 I/O modules (analog/digital) per module, remote I/O up to 12km. Compatible with Modbus, TCP/IP, and seamless integration with Foxboro, Honeywell and other DCS systems.
Hot-Swappable & Maintainable
Hot-swappable design allows replacement during operation to minimize downtime. Fits TRICON standard racks for easy installation and commissioning, reducing maintenance cost.
