I. Basic Positioning

Type: TDI (Transient Data Interface) transient data interface module

Series: 3500 system (not 7200), half-height card, occupying 1 slot

Function: Transmits steady-state + transient vibration/displacement data from all 3500 monitoring cards (40M/42M/44M, etc.) to the upper-level software (System 1, TDXnet, configuration software)

Alias: 72358‑51 = 3500/22M (commonly used model)

II. Core Functions

Data Acquisition: Continuously collects steady-state + transient dynamic data from all M-series monitoring cards (3500/40M, 42M, 44M, etc.)

Protocol Conversion: Replaces the old system 3500/20 (RIM) + communication processor, combined into one unit

Upper-level Interface: Connects to System 1 status monitoring and diagnostic software, 3500 configuration software, TDXnet

TMR Redundancy: In a three-redundancy (TMR) architecture, automatically compares 3 data paths, and triggers an alarm in case of an anomaly

III. Model Description (72358‑XX)

72358: Basic component number

‑XX: Tail suffix defines version/function:

72358‑51: The most common, 3500/22M standard TDI

Other tail suffixes: Correspond to different firmware / interface / regional versions

IV. Technical Parameters (3500/22M)

Slot: Half-height slot of 3500 frame, adjacent to the power supply side

Connection: Backplane bus connects M-series monitoring cards; front panel Ethernet / serial port connects to the upper computer

Data Rate: Supports high-speed transmission of transient waveforms, spectra, key signals

Redundancy: Supports TMR three-redundancy, automatic switching in case of failure

Environment: Operating 0–60℃, storage ‑40–85℃

Power Supply: Powered by 3500 frame +5V/+12V

V. Differences from 7200 Series (you previously asked about 72471/72489)

72358‑XX: 3500 system (new), communication / data interface card, half-height, 3500 frame used

72471‑B/BC, 72489‑XX: 7200 system (old), monitoring cards (shaft displacement / expansion difference), full-height, 7200 frame used

VI. Common Applications

Online status monitoring and fault diagnosis for key rotating machinery such as large steam turbine generators, compressors, fans, etc.

3500 system standard: 1 3500/22M (72358‑51) + multiple M-series monitoring cards
