BENTLY 146031-01 Transient Data Interface Module

BENTLY 146031-01 (3500/22M TDI module)
It is the core I/O and communication motherboard of the 3500/22M Transient Data Interface (TDI), part number 146031-01, often paired with 138607-01 to form a complete 3500/22M module.

1、 Basic Information
Model: 146031-01 (3500/22M TDI module body)
Brand: Bently Nevada (currently owned by Baker Hughes)
Series: 3500 Mechanical Protection System
Type: Transient Data Interface (TDI) I/O Module (3500/22M Core Board)
Status: Discontinued (DISC), original factory has no new products; The market is mainly dominated by second-hand/refurbished
Positioning: Installed in the RIM slot of the 3500 rack (adjacent to the power supply), with a slot width of 1
Matching: Combined with 138607-01 (front panel/interface board) to form a complete 3500/22M
2、 Core functions
Data collection: In conjunction with M-series monitoring cards (3500/40M, 42M, 45M, 50M), collect steady-state and transient (waveform) data of vibration, displacement, speed, and key phases.
Communication gateway: Upload data to System 1/3500 configuration software via Ethernet (10/100 Base-T); Integrate the original 3500/20 (RIM) with TDXnet functionality.
System control: Switch rack RUN/ROG mode; Provide front panel USB/serial port for local configuration.
Data storage: Standard static data capture; The optional Channel Enabling Disk supports high-resolution transient waveform storage.
3、 Technical parameters
Component composition: 146031-01 (motherboard)+138607-01 (front panel)=3500/22M

Dimensions (H × W × D): 133 × 72 × 229mm
Weight: Approximately 1.8kg (whole truck)
Certification: CSA, CE, ATEX; Compliant with API 670

4、 Model substitution and compatibility
Shutdown replacement: no direct replacement; Recommended new project 3500/22E (enhanced TDI)
Compatible modules: M-series including 3500/40M, 42M, 45M, 50M, 53M, etc
Firmware Matching: Requires compatibility with 3500 rack firmware version
5、 Procurement and Application
Market situation: New original products are scarce; Used/refurbished for approximately $1200- $2000, with a warranty of 3-12 months
Typical applications: Vibration monitoring and fault diagnosis of high-speed rotating machinery such as steam turbines, gas turbines, centrifugal compressors, generators, etc
6、 Model discrimination
3500/22M: Complete TDI module=146031-01 (motherboard)+138607-01 (front panel)
146031-01: TDI Core I/O and Communication Board (excluding front panel)
138607-01: TDI front panel (including interfaces and indicator lights)
