Technical Specifications
| 146031-02 | is a Transient Data Interface Module designed and manufactured by Bently Nevada as part of the 3500 Series. It is used for monitoring seismic activity and serves as the interface between the 3500 monitoring system and compatible software, such as System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software. The 3500/22M Transient Data Interface (TDI) integrates the functions of a 3500/20 Rack Interface Module (RIM) with the data collection capabilities of a communication processor like TDXnet. |

Why I/O Module Configuration Matters
The Bently Nevada 146031-02 is an I/O module that handles signal conversion between field devices and the control system. What makes ordering a replacement tricky is that Bently Nevada uses configuration codes in their part numbers — the base model might be the same, but suffix codes can change the input voltage range, output type, channel count, isolation rating, or communication protocol. Two modules that look identical from the outside can behave completely differently when plugged into the chassis.
Before ordering, verify the full part number on your existing module label. Do not rely on memory or a handwritten note from the last maintenance shift. Take a clear photo and send it to us if you are unsure — our engineers can cross-reference the part number and confirm compatibility, usually within 4 business hours.
Every I/O module we ship is factory-sealed and functionally tested on a live Bently Nevada rack: all channels exercised with calibrated signal sources, communication verified, 48-hour burn-in at 55°C. Printed test report included. 12-month warranty. Worldwide shipping within 24 hours.
Compatible Parts — Same System
These modules share the same system family as the 146031-02. Commonly ordered together for complete rack builds or spare parts kits.
