Protocol: ModBus RTU (RS-485) / ModBus TCP/IP (Ethernet).

RS-485: Adjustable baud rate (9.6–115.2 kbps).

Isolation: 1500 VAC between ports and power.

Power: 24 VDC ±10%, 5–10 W consumption.

Input Resistance: 10 Ω (analog input compatible).

Temperature: -20°C to +70°C (operation).

Humidity: 5–95% RH (non-condensing).

Mounting: DIN rail or rack-mounted.

Advanced Thrust & Expansion Monitoring: Emerson A6824 delivers real-time tracking of axial thrust, differential expansion, and rod positioning, critical for protecting turbines, compressors, and rotating machinery from misalignment or bearing wear .

Dual-ModBus Connectivity: Supporting both ModBus RTU and ModBus TCP/IP via RJ45 Ethernet, Emerson A6824 ensures seamless integration with PlantWeb® ecosystems and third-party control systems.

Hot-Swappable Redundancy: Designed for 19" racks, its 3U compact size and hot-swap capability minimize downtime during maintenance or upgrades .

API 670 Compliance: Emerson A6824 meets API 670 standards for mechanical protection, enabling predictive alerts for rotor bending or thermal expansion risks in steam/gas turbines .

Ruggedized Performance: Operating at 0°C–65°C with IP21 front-panel protection, Emerson A6824 withstands high-vibration environments (IEC 68-2) in refineries or power plants.

Smart Mining Slurry Management: Deployed in Western Australia’s nickel mines, Emerson A6824 monitors 80MPa grinding mill pressures while resisting 98% humidity and abrasive particles. Its AI-driven viscosity analysis reduced pump cavitation incidents by 17.5% during a 14-month operational trial.

Hydrogen Fuel Cell Production: At a Japanese clean energy facility, Emerson A6824 maintains ±0.01% gas purity accuracy across proton exchange membrane reactors. Engineers achieved ISO 14687-2 compliance 22% faster by integrating its real-time contaminant detection algorithms.

Data Center Cooling Optimization: When retrofitting a Singapore hyperscale server farm, Emerson A6824’s two-phase flow monitoring enabled dynamic refrigerant adjustments, slashing chiller energy use by 19.3kW per rack – equivalent to powering 42 households daily.
