BENTLY 135137-01
Product introduction
The 135137-01 from Bently Nevada is a high-density signal input module designed as a central data acquisition component in 3500 Machinery Protection Systems. This rack-mount module serves as the primary interface for analog sensor signals, converting conditioned inputs from vibration transmitters, temperature sensors, and pressure transducers into digital data for processing and analysis. Bently Nevada’s 135137-01 acts as the critical data entry point in the monitoring chain, receiving standardized 4-20 mA signals from transmitters like the 125680-01 and raw voltage outputs from sensors, then converting them into high-resolution digital data that flows to protection logic solvers and communication gateways.
Bently Nevada’s 135137-01 addresses the need for reliable multi-channel data acquisition in complex machinery monitoring applications. Its 8-channel design with simultaneous sampling ensures time-correlated measurements across all inputs, essential for analyzing vibration patterns across multiple machinery components. When integrated with 125680-01 vibration transmitters, this module provides the high-fidelity data that enables accurate machinery health assessment, with information distributed through 3500/34 gateways to both local protection systems and enterprise analytics platforms.
Core advantages and technical highlights
High-density data acquisition: The 135137-01 offers 8 independent analog input channels in a single rack slot, maximizing the monitoring capacity of 3500 system racks. This high channel density reduces the number of modules required for comprehensive machinery monitoring, saving rack space and reducing system complexity in applications with multiple measurement points.
Simultaneous high-speed sampling: All 8 channels sample simultaneously at 10 kHz with 16-bit resolution, ensuring time-correlated data capture that preserves the phase relationships between vibration signals from different machinery components. This capability is critical for analyzing machinery train dynamics where vibration patterns propagate through connected components.
Flexible input configuration: Each channel can be independently configured for either 4-20 mA current inputs (ideal for connecting to 125680-01 transmitters) or 0-10 VDC voltage inputs, providing seamless integration with diverse sensor types without requiring external signal converters. Channel-specific configuration allows mixed sensor technologies within a single module.
Advanced diagnostic capabilities: The module incorporates comprehensive self-diagnostics and channel monitoring that detects open circuits, short circuits, and signal out-of-range conditions. These diagnostics provide early warning of sensor or wiring faults, enabling proactive maintenance before measurement loss occurs—critical for maintaining protection system integrity.
Typical application scenarios
In power generation turbine systems, the 135137-01 serves as the primary data acquisition module for bearing vibration monitoring, receiving 4-20 mA signals from 125680-01 transmitters connected to 133396-01 accelerometers. Its simultaneous sampling captures vibration data from multiple bearing positions across the turbine train, preserving phase relationships essential for identifying rotor imbalance and misalignment. The digitized data is processed locally for protection actions and transmitted via 3500/34 gateways to plant DCS and diagnostic systems.
Oil and gas processing facilities utilize the 135137-01 in compressor health monitoring systems, where its mixed input capability handles both 4-20 mA vibration signals from remote transmitters and 0-10 VDC pressure measurements from local transducers. The module’s diagnostic features detect wiring faults in extended cable runs, ensuring reliable monitoring of critical compression equipment. Its high-density design allows comprehensive monitoring of compressor, motor, and gearbox health from a single rack slot.
Manufacturing plants deploy the 135137-01 in production line monitoring systems, where it aggregates vibration data from multiple motors and gearboxes via 125680-01 transmitters. The module’s 8 channels support monitoring of an entire production cell, with simultaneous sampling enabling correlation of vibration patterns between interconnected equipment. Digitized data flows to both local protection relays and enterprise systems, supporting both immediate fault response and long-term predictive maintenance programs.

Installation, configuration and maintenance instructions
Installation preparation: Before installing the 135137-01, verify compatibility with the target 3500/20 rack and ensure firmware versions match other system components. Confirm the rack has an available slot and that the 3500/05-01-02-00-00-01 power supply can accommodate the additional load. Required tools include a screwdriver set, torque wrench, and laptop with 3500 configuration software. Inspect the module for shipping damage, particularly checking backplane connectors and front panel indicators.
Mounting and wiring: Insert the 135137-01 into an available slot in the 3500/20 rack, securing it with front panel screws torqued to specified values. Power is supplied through the rack backplane, eliminating the need for external power wiring. Connect field signals to the terminal block using shielded twisted-pair cable, with separate runs for 4-20 mA inputs from 125680-01 transmitters and other analog signals. Ground cable shields at the module end only to prevent ground loops.
Configuration procedures: Power on the 3500 system and establish communication with the 135137-01 using configuration software. Configure each channel for the appropriate input type (4-20 mA or 0-10 VDC) based on connected sensors. Set scaling parameters to convert raw input values to engineering units (e.g., mm/s, g, or °C). Configure alarm thresholds and diagnostic parameters for each channel, enabling fault detection for critical measurement points. Save and backup configuration settings after verification.
Maintenance suggestions: Include the 135137-01 in quarterly system inspections, verifying front panel status indicators show normal operation. Check for error codes in system diagnostics that indicate channel faults or communication issues. During scheduled shutdowns, verify calibration using the 330130-080-00-00 fixture, injecting known signals into each channel and confirming accurate measurement. Clean ventilation openings to maintain proper cooling. Check for firmware updates annually and apply during maintenance windows to ensure compatibility with system components like 3500/34 gateways.
