Required Components:
3500/92 Main Module (136180-01): Must be paired with the Bently Nevada 136188-02 to provide communication protocol processing capabilities.
3500 Rack and Power Supply: Such as the 3500/05 rack frame and 3500/15 power supply module, which power the system and provide physical mounting slots.
Data Source Modules:
Vibration Monitoring: 3500/42M Proximitor Monitor (Shaft Displacement/Vibration)
Temperature Monitoring: 3500/60M Temperature Module (Bearing/Winding Temperature) Data is collected by these modules and forwarded to the control system by the Bently Nevada 136188-02.
Software Tools:
System 1™ Software: Configures the Bently Nevada 136188-02 register map and enables historical data analysis via Ethernet.

Analysis of alternative models:
Advantages: The RS485 interface of 136188-02 supports multi-node series connection (such as fan group control), and the cost is lower than the fiber optic solution; compared with 136188-01, it is more suitable for wide-area deployment such as oil and gas pipelines.
Limitations: If the host only needs RS232 communication (such as old PLC), 136188-01 is more economical; it is recommended to directly use 136188-02 for new projects to retain scalability.
