The 3500/22M Transient Data Interface (TDI) is the gateway module for the Bently Nevada 3500 Series rack. It interfaces with the 3500 Configuration Software for module setup, calibration, and fault diagnostics. The TDI also streams continuous static and dynamic waveform data to System 1 condition monitoring software for predictive analytics.
The 3500/22M supports both legacy serial Modbus RTU and modern Modbus TCP / Ethernet connectivity. It is the central data hub for any 3500 rack connected to a DCS, ESD, or asset management system.
