Core Technical Parameters

Main Product Features

3.1 Upgraded High-Precision Speed Measurement

The latest revision 288062-02 adopts upgraded high-resolution pulse sampling and optimized frequency conversion algorithm, effectively reducing signal jitter and sampling deviation compared with older versions. It maintains ultra-stable RPM output under variable speed, vibration and fluctuating field conditions, supporting accurate measurement from complete standstill to ultra-high-speed rotation, ensuring long-term consistent monitoring accuracy for critical rotating machinery.

3.2 Dual Independent Redundant Channel Design

Equipped with two physically and electrically independent monitoring channels, the module supports dual redundant speed acquisition for a single machine or simultaneous speed monitoring of two separate equipment sets. Each channel features independent threshold configuration, signal processing and fault diagnosis, providing dual verification for overspeed protection logic and greatly improving the safety and reliability of machinery protection loops.

3.3 Multi-Dimensional Safety Protection Logic

The 3500/50 (288062-02) integrates comprehensive protection functions including adjustable overspeed alert, critical overspeed trip, zero-speed standstill interlock and acceleration/deceleration anomaly detection. It can quickly capture abnormal operating states such as equipment overspeed runaway, sudden speed drop and unexpected startup, outputting reliable hardwired trip signals to trigger equipment interlock shutdown and prevent mechanical damage, blade collision and bearing failure.

3.4 Full-Link Intelligent Self-Diagnosis

This upgraded module enhances full-loop diagnostic coverage, supporting real-time detection of sensor disconnection, signal attenuation, pulse distortion, wiring faults and internal circuit anomalies. It generates precise fault codes and logs, uploading diagnostic data to the upper monitoring system for fast troubleshooting. The improved self-test mechanism eliminates monitoring blind spots and ensures 100% availability of the speed protection loop.

3.5 Enhanced Industrial Anti-Interference Performance

With upgraded EMC electromagnetic compatibility and surge suppression circuit design, the 288062-02 revision provides stronger resistance against on-site electromagnetic interference, high vibration, power fluctuation and high-temperature environmental impact. It ensures distortion-free pulse signal acquisition and stable data output in complex industrial workshops, adapting to long-term continuous operation in harsh field conditions.

3.6 Flexible Configuration & Low Maintenance Cost

All monitoring parameters, alarm thresholds and protection logic can be remotely configured, adjusted and calibrated via official 3500 configuration software. It supports real-time data display, historical trend recording and fault log query. Standard rack plug-and-play installation simplifies on-site commissioning, module replacement and daily maintenance, effectively reducing system operation and maintenance costs.
