Bently Nevada|3500/22 161580-01| Transient Data Interface (TDI)

Bently Nevada 3500/22M 161580-01 Transient Data Interface (TDI)

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

Features

• Supports real-time data transfer to System 1 Software and 3500 Configuration Software
• Allows dynamic waveform capture (requires Channel Enabling Disk for transient data)
• Interfaces with M-series monitors (e.g., 3500/40M, 3500/42M)
• Non-critical to protection; occupies Slot 1 in the rack
