The Bently Nevada 3500/22M-01-01-00, also cataloged as the 138607-01+146031-01 Transient Data Interface (TDI) Module, operates as a communication processor and rack interface component for data collection and configuration within the 3500 machinery protection system.

Model Configuration

The 3500/22M-01-01-00 ordering designation combines the standard TDI module ordering option 3500/22-01 (part number 138607-01) with the 10Base-T/100Base-TX copper Ethernet I/O module ordering option 01 (part number 146031-01) and agency approval option 00 (None). This configuration replaces standalone rack interface modules and communication processors, providing Ethernet networking and USB configuration access for rack data management.

Hardware Specifications

Communication Protocols and Rack Integration

The TDI module serves as the primary gateway between 3500 rack monitors and software platforms such as System 1 Condition Monitoring and Diagnostic software and 3500 System Configuration software. It combines rack interface functions with high-speed waveform data collection, supporting BN Host Protocol and BN TDI Protocol over Ethernet TCP/IP. The module occupies Slot 1 adjacent to the power supplies, managing rack configuration keylocks, system contacts (Trip Multiply, Alarm Inhibit, Rack Reset), and an OK relay for overall rack health annunciation.

Ordering Information and Package Contents

• 1 x Bently Nevada 3500/22M Transient Data Interface Module (138607-01)
• 1 x 3500/22M 10Base-T/100Base-TX Copper Ethernet I/O Module (146031-01)
• 1 x USB-A to USB-B Cable (123M4610, 3 meters / 9.8 ft)

Installation and Electrical Integration

The TDI module installs exclusively into Slot 1 of a 3500 rack, directly adjacent to the power supply module. The matching I/O module occupies the corresponding rear slot. When upgrading from an older 3500/20 Rack Interface Module (RIM), ensure the old RIM and its I/O are fully removed before inserting the TDI I/O and module to prevent hardware damage. Connect Ethernet cabling via the RJ-45 port supporting distances up to 100 meters (328 feet). When utilizing the front USB port, ensure the connected computer operates on battery power to avoid ground loops and maintain chassis isolation.
