Parameters (Specifications) Brand: Emerson (Rosemount) Product Series: FDM (Field Diagnostic Monitor) Model Number: FDM11A720BAC2V12EZZMCTG Device Type: Industrial Vibration and Process Variable Monitor/Transmitter Summary of Key Specifications Inputs: 4 Accelerometer Inputs: For high-frequency vibration sensors (ICP type). 4 4-20 mA Analog Inputs: For external process transmitters (pressure, temperature, flow, etc.). Outputs/Communications: Ethernet: For local configuration and data access (Modbus TCP/IP typically). 4-20 mA Outputs: (Optional, depending on config) for retransmitting calculated diagnostic values. Alarm Relays: Typically includes relays for alerting on fault conditions. Power Supply: 24 VDC (nominal), 10-30 VDC range. Enclosure Material: Aluminum Enclosure Rating: NEMA 4X (IP66) - Weatherproof and dust-tight. Mounting: 2-inch pipe mount bracket (included). Diagnostic Capabilities: Mechanical faults: Bearing condition, imbalance, misalignment, looseness. Process faults: Cavitation, flow surges, air entrainment, pump performance degradation. Data Processing: On-board FFT (Fast Fourier Transform) analysis for vibration spectrum. Operating Temperature: -40°C to 70°C (-40°F to 158°F) typical. Software Compatibility: Compatible with AMS Device Manager and Plantweb Optics for asset management. Application Notes: Predictive Maintenance: This device is not a flow meter; it is a diagnostic monitor used to predict when a pump or motor will fail. Installation: It is typically mounted near the equipment being monitored and connected to accelerometers glued or stud-mounted on the machinery. Integration: It integrates with Emerson's digital plant architecture to feed health data directly to control rooms or maintenance systems.
