Bently Nevada 3500/22M — 146031-01 Transient Data Interface I/O Module
Product Overview
The 146031-01 is a 10Base-T/100Base-TX Ethernet I/O Module designed as an integral component of the Bently Nevada 3500/22M Transient Data Interface (TDI) system. It serves as the critical communication bridge between the 3500 machinery protection and monitoring system and host software platforms, including System 1 Condition Monitoring and Diagnostic Software and 3500 System Configuration Software.
By combining the functionality of a 3500/20 Rack Interface Module (RIM) with the data acquisition capabilities of a dedicated communication processor, the TDI enables seamless, real-time transmission of both static and dynamic machinery data over standard Ethernet infrastructure.
Key Features & Main Characteristics

Important Installation Notes
CAUTION — Upgrade Advisory: When upgrading an existing 3500 rack from a 3500/20 RIM to a 3500/22 TDI, the RIM I/O module must be removed before installing the TDI I/O module. Failure to do so will damage the TDI. The recommended sequence is: (1) Remove RIM, (2) Remove RIM I/O, (3) Insert TDI I/O, (4) Insert TDI.
Signal Grounding: The I/O module includes a 2-pin Signal Common terminal. When connecting to instrument ground, the selector switch on the Power Input Module (PIM) must be set to the «HP» position to isolate Signal Common from chassis (safety) ground.
Summary
The Bently Nevada 146031-01 is a robust, rack-integrated Ethernet I/O module that forms the data communication backbone of the 3500/22M Transient Data Interface. By enabling high-fidelity static and dynamic data transfer between the 3500 monitoring system and host diagnostic software, it empowers asset reliability teams to perform comprehensive machinery condition assessment — from routine steady-state trending to advanced transient event analysis — all within a compact, single-slot form factor designed for the demands of modern industrial environments.
