Bently Nevada 3500/22M 164466-01 Transient Data Interface (TDI)

The Bently Nevada 3500/22M is an interface module that facilitates communication between the 3500 monitoring system and external software applications for dynamic data collection, including transient waveforms.

Features

• Supports real-time data transfer to System 1 Condition Monitoring & Diagnostic Software.
• Enables steady-state and transient waveform capture.
• Interfaces with M-series monitors like 3500/40M, 3500/42M.
• Non-critical to machinery protection; occupies Slot 1 in the rack.
