The 3300/55-03-04-14-14-00-00-07-00 is a rack-mounted dual-channel velocity monitor designed for continuous monitoring of absolute machinery casing vibration. It processes signals from velocity transducers to provide real-time vibration data, enabling early detection of mechanical faults in rotating equipment such as pumps, motors, and fans. Its outputs are compatible with PLCs, DCS systems, or analog recorders, making it ideal for preventive maintenance and machinery protection in industrial environments.

Dual Independent Channels: Each channel has dedicated OK LEDs to indicate transducer health.
Alarm Logic: Configurable "Danger" relays for latching or non-latching operation.
Recorder Integration: 4–20 mA analog outputs allow seamless integration with PLCs, DCS, or chart recorders.
Maintenance-Friendly: Includes bypass switches for individual channel servicing without shutting down the system.
Hazardous Area Compliance: CSA/NRTL/C certified for Class 1, Div 2 environments.
Does this module support metric units?
The standard configuration is scaled in inches per second (in/s). Metric scaling (mm/s) is available through optional configurations or by adjusting internal scale factors.
Can I use this with accelerometers instead of velocity sensors?
No. This module is specifically filtered and calibrated for velocity signals. For acceleration monitoring, the 3300/50 Dual Accelerometer Monitor should be used.
How is the recorder output powered?
The 4–20 mA recorder output is internally powered by the module, eliminating the need for external loop power for standard analog monitoring.
