Product Overview

FC‑TCNT11 is redundant‑controller IOTA terminal base assembly for Honeywell Safety‑Manager SC‑S300 safety‑instrumented‑system. It accepts dual FC‑SCNT01 / FC‑SCNT02 safety‑CPU modules, provides physical termination for redundant safety‑bus, host‑communication and engineering‑workstation links. It executes real‑time primary‑standby CPU‑state synchronization and millisecond‑level bumpless automatic failover upon main‑controller hardware‑failure. It is core hardware for SIL3‑rated ESD, F&G and burner‑management‑systems. Available as refurbished and new‑old‑stock spare parts for safety‑system‑retrofit and maintenance.

Application Notes

‑ Must pair with matching FC‑SCNT01 / FC‑SCNT02 safety‑CPU modules. ‑ Follow Honeywell SIS engineering‑manual for redundant‑system configuration. ‑ ESD anti‑static handling is mandatory during module‑replacement. ‑ Typical deployment: petrochemical plant ESD‑system, power‑plant BMS burner‑management‑system spare‑part stocking.
