4. Protection Grade: IP20 (standard)

5.Mounting Method: DIN rail mount or panel mount

Characteristics

1. Compact integrated structure, small footprint, easy installation and retrofit

2. Industrial anti-interference performance, stable operation in high-vibration, dusty and humid environments

3. Independent dual-threshold alarm (Alert & Danger) with adjustable delay to avoid false alarms from transient interference

4. Built-in self-diagnosis function, real-time sensor status monitoring and fault warning

5. 200-entry event log for equipment failure traceability and predictive maintenance analysis

6. Configurable measurement range, filter parameters and alarm thresholds via software

Functions

1. Real-time continuous monitoring of vibration displacement, velocity, acceleration and equipment temperature

2. Early detection of mechanical faults: bearing wear, rotor imbalance, shaft misalignment, loose parts, abnormal temperature rise

3. Two-level alarm and interlock protection to trigger shutdown or warning when equipment operates abnormally

4. Data transmission to upper industrial control systems via analog signal or digital Modbus communication

5. On-site status display via LED indicators and attached display screen

Product Advantages

1. Cost-effective monitoring solution, lower investment compared with high-end 3500 series monitors, suitable for balance-of-plant equipment

2. Wide compatibility with mainstream industrial sensors, no need for additional signal conversion modules

3. Flexible configuration, adapts to various types of auxiliary machinery monitoring scenarios

4. High reliability and long service life, proven performance in global industrial applications
