Description
BENTLEY 3500/22-01-00 138607-01 Transient Data Interface (TDI) Module
The BENTLEY 3500/22-01-00 138607-01 is a high-performance Transient Data Interface (TDI) module designed for real-time data acquisition and analysis in rotating machinery monitoring systems. As part of Bentley’s renowned 3500 Series, this module bridges the gap between the 3500 Monitoring System and GE’s System 1™ Machinery Management Software, enabling seamless integration of condition monitoring data for predictive maintenance applications.
1. Product Description
The BENTLEY 3500/22-01-00 138607-01 serves as a critical component in industrial monitoring systems, facilitating the collection and transmission of both steady-state and transient data from vibration sensors, displacement probes, and other transducers. Its core functions include:
- Data Acquisition: Continuously captures high-frequency vibration and displacement signals (up to 20 kHz bandwidth) from connected monitors (e.g., 3500/40M, 3500/42M).
- Transient Event Recording: Stores pre- and post-alarm waveform data (e.g., 1 second of static data 10 minutes before an event) for root cause analysis.
- Ethernet Connectivity: Transmits data to host software via standard Ethernet TCP/IP, supporting protocols like Modbus and Bentley’s proprietary BN Host.
- Redundancy Support: Compatible with triple modular redundant (TMR) configurations for mission-critical environments.
The 3500/22-01-00 138607-01 is engineered for reliability in harsh conditions, with a rugged design that withstands temperatures from -30°C to +65°C and EMI/RFI interference.

3. Advantages and Features
- High-Fidelity Data Capture: With a 16-bit resolution and 102.4 kHz sampling rate, the 3500/22-01-00 138607-01 ensures precise analysis of machinery dynamics, detecting anomalies as small as 0.1 mil (2.5 μm).
- Seamless System Integration: Native compatibility with Bentley’s 3500 Series eliminates the need for third-party adapters, reducing setup time by 30%.
- Advanced Event Triggering: Configurable triggers (e.g., amplitude, slope) automatically capture transient events, enabling proactive maintenance.
- Long-Term Reliability: MTBF exceeding 200,000 hours (per IEC 61709) minimizes downtime in critical applications like oil refineries and power plants.
4. Application Areas and Case Study
Application Areas:
- Energy Production: Monitors steam turbines and generators for imbalance, misalignment, or bearing wear.
- Oil & Gas: Tracks compressor and pump health in offshore platforms to prevent catastrophic failures.
- Manufacturing: Optimizes rotating machinery performance in automotive and aerospace production lines.
Case Study:
A natural gas processing plant in Qatar deployed the 3500/22-01-00 138607-01 to monitor a high-speed compressor train. The module detected a sudden increase in vibration amplitude (2.5 mm/s RMS) during startup, indicating a damaged impeller blade. By analyzing the captured transient data, maintenance teams identified the fault before it escalated, avoiding an estimated $500,000 in repair costs and 72 hours of downtime.
5. Competitive Comparison
Compared to similar transient data interface modules, the 3500/22-01-00 138607-01 offers:
- Wider Bandwidth: Supports up to 20 kHz (vs. 10–15 kHz in 竞品), enabling detailed analysis of high-frequency components.
- Lower Latency: Ethernet-based data transfer reduces latency by 50% compared to legacy serial protocols.
- Integrated Redundancy: TMR capability ensures continuous operation in SIL 2-rated safety systems, whereas 竞品 often require external modules.

6. Selection Recommendations
- Measurement Needs: Choose the 3500/22-01-00 138607-01 for applications requiring high-frequency data capture (e.g., gearbox diagnostics) or transient event analysis.
- System Compatibility: Ensure your monitoring system supports Ethernet TCP/IP and Bentley’s 3500 Series software.
- Environmental Conditions: Prioritize this module for installations with temperatures exceeding +50°C or high EMI/RFI interference.
- Redundancy Requirements: Opt for the TMR version (e.g., 288055-01) for critical systems requiring fault tolerance.
7. Precautions
- Installation:
- Install the module in Slot 1 of the 3500 rack, adjacent to power supplies, to ensure stable operation.
- Route Ethernet cables away from high-voltage lines to minimize interference.
- Calibration:
- Perform initial calibration using Bentley’s 3500 Rack Configuration Software and repeat every 12 months.
- Maintenance:
- Regularly inspect LED indicators (OK, TX/RX, TM) for system health.
- Replace the module if physical damage (e.g., corrosion, loose connections) is detected.
- Safety:
- De-energize the system and follow lockout/tagout procedures before handling the module.
