- Channels: 4 independent vibration inputs
- Sensor Compatibility: Accelerometers, velocity sensors, and eddy current probes
- Relay Outputs: Programmable alert and danger relays
Functional Features
- Multi-Sensor Flexibility: Software-configurable to accept various sensor types and measurement units (Peak-Peak, RMS, etc.).
- Local Display: Features a front-panel display for real-time viewing of vibration values and alarm status.
- Analog Outputs: Provides buffered 4-20 mA outputs for integration with plant control systems.
Application Scenarios
Widely used in power plants, chemical facilities, and manufacturing plants to protect auxiliary equipment such as fans, blowers, water pumps, and motors.
Performance Parameters
- Measurement Accuracy: High precision for general machinery protection
- Configuration Storage: Non-volatile memory retains settings during power loss
Material Composition
Housed in a robust, industrial-grade enclosure designed for panel mounting, providing excellent EMI shielding and mechanical protection.
Structural Characteristics
Compact standalone module with front-panel LED status indicators, local display, and rear terminal blocks for sensor and relay wiring.
Working Principle
Receives analog signals from vibration sensors, conditions the signals, converts them to digital values, and compares them against user-defined alarm thresholds to trigger relays or analog outputs.
Installation Requirements
Mount in a standard control panel. Connect sensors using shielded cables and ensure proper grounding to prevent electrical noise interference.
Precautions for Use
Configuration parameters must be defined using Bently Nevada configuration software. Verify sensor type and sensitivity settings match the installed field devices.
