Key Features

32MB large memory and high-speed RISC processor, stable for medium-scale multi-loop process control and data logging.

Dual independent Ethernet ports separate HMI, SCADA and field device communication to avoid single network breakdown.

Multi-protocol compatibility enables seamless connection with inverters, analyzers and third-party remote RTU systems.

RS232 local debug port supports firmware upgrade, parameter backup and offline fault analysis on site.

Front panel LED indicators display power, bus link and hardware fault status for quick troubleshooting.

Dedicated TP830 baseplate simplifies rack wiring and supports hot-swap under proper system configuration.

Full compatibility with all AC800M series I/O, communication and safety modules for flexible system expansion.

Anti-vibration conformal coated PCB, stable 24/7 continuous operation in dusty and humid industrial control rooms.
