3500/22M 288055-01 Transient Data Interface (TDI) module

The BENTLY 3500/22M 288055-01 is an advanced Transient Data Interface (TDI) module in Bently Nevada’s 3500 Series Rotating Machinery Protection & Monitoring System. As a dedicated hub for transient data acquisition, processing, and transmission, it is engineered to capture high-fidelity steady-state and transient (waveform) data from 3500 Series M-type monitors (e.g., 3500/40M, 3500/42M, 3500/44M). The "M" in its model denotes optimized compatibility with M-series monitors, while the part number 288055-01 represents an upgraded standardized configuration—enhancing data storage capacity, communication redundancy, and environmental resilience compared to earlier variants. It is critical for in-depth machinery condition analysis (e.g., startup/shutdown monitoring, fault root-cause diagnosis, and predictive maintenance) in harsh industrial environments. Below is its comprehensive detailed information:

I. Core Technical Parameters

Category	Specific Specifications
Basic Identification	- Model: 3500/22M (Transient Data Interface Module)- Part Number: 288055-01- Applicable System: Bently 3500 Series (compatible with 3500/10 single-frame and 3500/20 multi-frame racks)- Core Role: Transient waveform capture, steady-state data aggregation, and bidirectional communication with upper-level systems (e.g., EnerVista Machinery Health software, DCS/SCADA)
Data Acquisition Performance	- ADC Resolution: 16-bit (ensures high-fidelity waveform reproduction, minimizing signal distortion)- Sampling Rate: Configurable 1 kHz ~ 125 kHz (per channel); supports dynamic rate adjustment (e.g., 10 kHz for low-speed startup, 100 kHz for high-frequency fault detection)- Data Storage: 4 GB on-board industrial-grade flash memory (stores up to 20,000 transient waveform files or 2 years of steady-state historical data; supports cyclic overwriting for long-term deployment)- Supported Data Types:- Transient: Vibration time-domain waveforms, keyphasor-synced displacement profiles, impact shock signals- Steady-state: Peak-to-peak vibration, RMS velocity, average temperature, real-time speed, alarm status (Warning/Danger)
Keyphasor & Speed Sync	- Keyphasor Inputs: 4 independent, isolated Keyphasor signal inputs (compatible with 3500/25 Keyphasor modules)- Speed Range: 0.1 rpm ~ 30,000 rpm (synchronized with 3500/50/53 speed/overspeed modules)- Phase Alignment Accuracy: ±0.05° (enables precise correlation between transient waveforms and rotor position, critical for orbit analysis and order tracking)- Events per Revolution: 1 ~ 255 (programmable to match shaft reference features, e.g., 60-tooth gears, single keyways)
