Technical Parameters
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.
Operating Environment
Harsh Industrial Settings: The Emerson A6824 operates flawlessly in temperatures from -35°C to +180°C, making it ideal for power plants, offshore platforms, and oil refineries.
Durability: Its IP65-rated enclosure resists dust, moisture, and mechanical stress, ensuring longevity in corrosive or high-vibration environments.
Key Features
Dual ModBus Support: Offers both TCP/IP and RTU communication (19.2 kbaud, 8 data bits) for flexible integration with SCADA or control systems.
High Precision: Provides 2 V/mm sensitivity (±1.5% deviation) for accurate data acquisition from connected sensors.
Redundancy Option: Configurable as primary/backup systems to prevent single-point failures, enhancing operational reliability.
Compatible Systems
AMS 6500 Integration: The Emerson A6824 reads parameters from all AMS 6500 modules (e.g., A6110, A6210) to build API 670-compliant protection systems.
Sensor Pairing: Works with eddy-current sensors (PR642X series) for displacement measurements in turbines and compressors.
Typical Applications
Turbomachinery: Monitors steam/gas turbines and compressors, transmitting real-time vibration data to prevent unplanned downtime.
Security Systems: Tracks tampering on fences or ATMs via vibration analysis, triggering NC alarms (12VDC/1A) for intrusions.
Installation & Maintenance
Quick Setup: Compact 4TE width design fits standard 19-inch racks, reducing cabinet space.
Low Maintenance: Hot-swappable modules and self-diagnostics minimize interventions, backed by a 1-year warranty.
