Product Description

High-Performance Communication and Waveform Capture

The 3500/22M (Model: 3500/22M) is a specialized Transient Data Interface (TDI) I/O module designed for the Bently Nevada 3500 Series Machinery Protection System. The 146031-01 (Part Number: 146031-01) functions as the essential rear interface for the TDI system, providing high-bandwidth Ethernet connectivity to bridge the monitoring rack with external condition monitoring software. This module is engineered to handle both static data and complex dynamic waveforms, enabling the high-resolution capture of transient events such as machinery start-ups and coast-downs that are critical for root-cause analysis.
