Bently Nevada 3500 22

1. Product Overview

The 3500/22 is a high-performance Digital Input/Output (Digital I/O) module or Transient Data Interface (TDI) module (different classification descriptions may exist in different documents). As the "neural center" of the 3500 system, it is responsible for collecting sensor data, executing digital logic control, and transmitting key data to the upper computer (SCADA/DCS system) for analysis.

2. Core Technical Parameters

Parameter	Specific Specifications	Remarks
Number of Channels	32 channels (configurable)	Supports multi-point monitoring to ensure full coverage of key equipment
Digital Input	Dry Contact or Voltage Input	Collects sensor status (e.g., on/off)
Digital Output	Relay Output or Voltage Output	Controls external equipment (e.g., cutting off power, activating alarms)
Sampling Rate	Up to 2 kHz	Able to capture fast transient events
Communication Interface	RS-485 (or M-Series Sensor Interface); Some models support Ethernet	Performs data communication with 3500 host or other systems
Operating Temperature Range	-40℃ - +70℃ (or +85℃)	Adapts to harsh industrial environments
Dimensions/Weight	Approx. 120mm x 80mm x 30mm / 1.2kg	Standardized modular design

3. Product Features

High Reliability and Industrial-Grade Design

Adopts a rugged chassis and protective design (such as IP67 protection level), enabling long-term operation in high-temperature, high-vibration, and dusty factory workshops.

Modularity and Compatibility

Designed as a standardized slot module, supporting hot-swapping for easy installation and maintenance.

Highly compatible with other modules of the Baker Hughes/Bently Nevada 3500 series (such as vibration sensor modules and temperature modules).

Flexible Logic Control

Supports user-defined digital logic (e.g., "If vibration exceeds the standard, cut off the power supply"), and executes protection actions directly on-site without upper computer intervention.

Real-Time Data Transmission

Can collect and transmit transient waveform data (such as shock waveforms) in real time, helping technicians quickly locate the fault source.

4. Main Application Fields

• Power Industry: Monitors core equipment such as steam turbines, generators, feed water pumps, and induced draft fans to prevent large-scale power outages caused by catastrophic failures.
• Oil and Gas: Used for key rotating equipment such as compressors, pumps, and turbines in oil refining, chemical industry, and offshore drilling platforms.
• Industrial Manufacturing: Monitors the operating status of large motors, fans, and conveying equipment to ensure the continuity of the production line.

5. Installation and Maintenance Recommendations

Installation Location

Should be installed in the rack or panel of the 3500 system to ensure tight connection between the module and the sensor, and keep away from high-temperature or strong magnetic interference sources.

Confirm that the module slot matches the system power supply specifications to avoid module damage caused by unstable voltage.

Maintenance Points

Regular Connection Inspection: Due to the harsh environment, it is necessary to regularly check the wear of dry contacts and relay contacts, and replace aging components in a timely manner.

Communication Status Monitoring: Use system software to monitor the communication health status of the module to prevent data loss caused by communication failures.

Spare Parts Management: Due to its key position in the system, it is recommended to keep a module of the same model on site.
