Key Features

Specialized bridge controller for interconnecting legacy INFI90 DCS and modern System 800xA control platforms, convenient for plant phased system renovation.

True dual-path network redundancy with ultra-fast automatic switchover, effectively eliminating single network failure risk for uninterrupted process production.

Independent onboard communication processor reduces master controller computing load, stable mass cyclic data exchange for large-scale I/O systems.

Built-in signal regeneration function enhances transmission quality, suitable for long-distance control cabinet layout in large chemical and power plants.

Multi-channel front panel LED status indicators for real-time power, link and fault alarm, convenient for on-site rapid troubleshooting.

SNMP network diagnosis function supports remote network monitoring, fault log collection and equipment status query via upper SCADA system.

Full galvanic isolation design for all network signal channels to suppress severe EMI interference generated by turbines, inverters and heavy-duty field equipment.

Rugged industrial coated PCB anti-vibration hardware design, stable 24/7 continuous long-term operation in dusty and humid central control rooms.
