Core Functions

Multi-signal compatibility: Each channel can be independently configured for voltage/current, suitable for temperature, pressure, level, and flow sensors.

Group isolation anti-interference: 8 channels are earth-isolated as a whole, suppressing common-mode interference, suitable for long-distance signal transmission.

Channel-level diagnosis: Breakdown, over-range, short-circuit detection, LED status indication, precise fault location.

Hot-swappable: ｒｅｐｌａｃｅ modules online without affecting system operation, reducing maintenance downtime.

System integration: Direct connection of ModuleBus bus to AC 800M, compatible with 800xA DCS, supports PROFIBUS DP and other protocols.

Typical Applications

Power: Thermal power plants / hydropower plants for temperature, pressure, flow, and level measurement.

Petroleum: Simultaneous high-precision acquisition of analog signals in refining and chemical processing plants.

Water treatment: pH, conductivity, level, and flow monitoring.

Metallurgy / Papermaking: Process monitoring of rolling lines and paper machines.
