Dual-Channel Velocity Measurement
This monitor processes signals from two independent velocity transducers simultaneously. Each channel measures absolute casing vibration for effective machinery condition assessment. The frequency response ranges from 2 Hz to 1 kHz, covering most rotating equipment speeds. Operators can configure each channel for specific input sensitivity and full-scale ranges. The module’s velocity measurement suits applications where casing vibration provides the best machine health indication.
Sensor Compatibility and Configuration
The 3300/55-06-01-11-16-02-02-00 accepts standard velocity transducers with 100 mV/in/s or 500 mV/in/s sensitivity. Users can select the appropriate sensitivity setting via internal configuration switches. This flexibility accommodates various sensor types commonly found in industrial monitoring systems. The module also provides built-in sensor fault detection for open circuits or shorted coils. This diagnostic feature alerts maintenance personnel to sensor issues promptly.
Alarm Setpoints and Relay Outputs
Four adjustable alarm setpoints (Alert and Danger per channel) provide comprehensive machinery protection. Users can set these thresholds using front-panel potentiometers for specific equipment requirements. Each channel features two SPDT relay outputs for external alarm annunciation and control. These relays activate when vibration velocity exceeds the configured setpoints. A bypass mode allows safe maintenance access without triggering false alarms.
Output Signals for System Integration
The module generates 4–20 mA analog outputs proportional to measured velocity for each channel. These outputs interface directly with DCS, PLC, and data acquisition systems. The standard 4–20 mA signal range simplifies integration with existing plant infrastructure. Operators can use these outputs for continuous trending and alarm monitoring in control rooms. The module’s output scaling matches typical vibration monitoring requirements.
Mechanical Design and Installation
This plug-in module measures 165 mm × 25 mm × 102 mm and weighs only 0.28 kg. It occupies a single slot in the standard 3300 series chassis. Front-panel LEDs provide visual status for power, channel health, Alert, and Danger conditions. A locking handle secures the module firmly in the chassis backplane. The compact design enables efficient use of rack space in monitoring cabinets.
Power and Diagnostic Features
The monitor draws 90 mA from the +24 V DC backplane supply. This low power consumption reduces heat generation and enhances reliability. Built-in sensor fault detection identifies open-circuit or short-circuit conditions in transducer wiring. Front-panel indicators display channel OK status for immediate fault recognition. These diagnostic capabilities minimize troubleshooting time and improve system availability.
Application Suitability
The 3300/55-06-01-11-16-02-02-00 suits vibration monitoring for motors, fans, blowers, and pumps. This module excels in applications where casing velocity provides the best failure indicator. The monitor also serves medium-speed machinery in chemical, power, and manufacturing plants. Its dual-channel design allows monitoring of two machine locations or components.
Operational Guidance
Insert the module into an available slot in the 3300 chassis. Connect velocity transducer cables to the appropriate front-panel terminals. Select the correct input sensitivity using internal configuration switches. Adjust Alert and Danger setpoints with front-panel potentiometers. Verify the 4–20 mA output correlates with applied vibration levels. Monitor front-panel LEDs for normal channel operation and alarm status.
