3. Technical Features and Advantages
Multi-Protocol Data Integration
The 3500/92 supports multiple communication protocols, including Modbus RTU (via serial ports) and Modbus TCP (via Ethernet), allowing direct connection to PLCs, HMIs, and cloud platforms. For example, in a power plant, it can transmit turbine vibration data to a DCS system via Modbus TCP while simultaneously sending bearing temperature data to a predictive maintenance platform via BENTLY’s proprietary protocol. This dual-channel transmission ensures both real-time control and long-term data analysis requirements are met .
Configurable Data Mapping
Its 8 Modbus registers can be freely mapped to 3500 system monitoring parameters (e.g., vibration amplitude, alarm status), enabling users to customize data transmission formats. In a chemical plant, users can configure Register 1 to output compressor radial vibration values and Register 2 to output bearing temperature alarms, simplifying upper-layer system integration .
High-Reliability Signal Isolation
Featuring galvanic isolation technology, the module prevents ground loops and electromagnetic interference (EMI), ensuring stable data transmission in harsh environments. For instance, in a steel mill with high electromagnetic noise, the 3500/92 maintains data integrity while connecting rolling mill drive motor vibration sensors to the monitoring system .
Modular Hot-Swap Design
Compatible with 3500 series full-size frames, the 3500/92 supports hot-swapping, allowing module replacement without system downtime. This is critical for continuous production environments like oil refineries, where maintenance must be performed during operation .
Real-Time Data Processing
Equipped with a high-performance processor, the module processes up to 256 data points per second, ensuring millisecond-level latency. In wind power generation, it enables real-time adjustment of pitch systems by transmitting wind turbine gearbox vibration data to the control system .
