- Integrated Relay Outputs: Features 6 programmable relay outputs for alarm and trip functions.
- Recorder Outputs: Includes 4 isolated 4-20 mA recorder outputs for trending.
Application Scenarios
Ideal for Balance of Plant (BOP) equipment such as cooling tower fans, boiler feed pumps, motors, and gearboxes in steel, power, and chemical processing industries.
Performance Parameters
- Vibration Frequency Range: 0.5 Hz to 25 kHz (Configurable 4-pole high-pass filter)
- Operating Temperature: -30°C to +65°C
Material Composition
Encased in a durable, industrial-grade enclosure providing excellent mechanical protection and EMI shielding.
Structural Characteristics
Compact panel-mount design featuring intuitive front-panel LED indicators for OK, Alert, and Danger statuses, along with standard rear terminal blocks for wiring.
Working Principle
The internal microprocessor conditions the analog signals from the connected sensors, calculates vibration variables (e.g., peak, RMS), and continuously compares these values against user-defined Alert and Danger thresholds to trigger relays and analog outputs.
Installation Requirements
Mount securely on a control panel. Sensor cables must be properly shielded and grounded to prevent signal noise. Ensure adequate ventilation around the unit for heat dissipation.
Usage Precautions
Use the dedicated 1900 Configuration Software for parameter setup. Perform regular functional tests on the relay outputs to ensure protection circuits remain operational.
