Bently Nevada 136711-01 Supply I/O Module | 3500 Series Rack Interface
Engineering Background: The Bently Nevada 3500 Series is the industry benchmark for continuous online machinery protection and condition monitoring in rotating equipment applications. Deployed across power generation, oil & gas, petrochemical, and heavy industrial facilities worldwide, the 3500 rack architecture provides modular, scalable vibration and process monitoring with SIL-rated safety integrity.
Product Positioning: The 136711-01 is the dedicated Supply I/O Module for the 3500 Series rack. It serves as the critical interface layer between the rack backplane power distribution and field I/O wiring, ensuring clean, conditioned signal routing and power delivery to downstream monitoring modules. This module is essential for any 3500 rack build-out or expansion requiring additional I/O capacity.

System Architecture & Signal Flow
Within the 3500 rack, the 136711-01 Supply I/O Module occupies a designated I/O slot and interfaces directly with the rack backplane. Field transducer wiring (accelerometers, proximity probes, velocity sensors) connects to the module’s terminal blocks. Conditioned signals are then routed via the backplane to the appropriate monitor modules (e.g., 3500/42M, 3500/45, 3500/50). The supply function ensures each connected channel receives stable excitation voltage, maintaining transducer bias and signal chain integrity across all operating conditions.
