Bently Nevada 3500/22M 138607-01 TDI Transient Data Interface Module

Product Description

Bently Nevada 3500/22M (P/N:138607-01) is the TDI Transient Data Interface module for 3500 machinery protection system. It integrates rack interface RIM and transient waveform acquisition function, installed adjacent to power supplies in 3500 rack. It manages rack configuration, collects steady-state and dynamic transient waveform data, transmits vibration data to System 1 condition monitoring software via Ethernet. It provides fault alarm through OK relay output. It is critical communication spare for turbine TSI monitoring. This model is obsolete, only surplus stock available on marketMade-in-Ch….

Application

1. Communication and rack configuration management for steam/gas turbine & compressor 3500 TSI protection rack;
2. Collect steady data and transient vibration waveform of shaft vibration, bearing vibration, thrust position and speed;
3. Link with System 1 diagnostic software for rotor fault analysis, spectrum and waveform review;
4. Rack health alarm, relay status transmission to DCS;
5. Spare replacement and retrofit for legacy 3500 systems in power plants and petrochemical sites.
