Bently Nevada 146031-01 Ethernet I/O Module | 3500 TDI Interface

Product Description

The Bently Nevada 146031-01 is a high-performance Ethernet I/O module designed for the 3500/22M Transient Data Interface (TDI). It serves as the primary communication bridge between the 3500 Series Machinery Protection System and System 1 condition monitoring software, as well as 3500 Configuration Software. This rear-mounted module consolidates the functions of the older 3500/20 Rack Interface Module (RIM) and legacy communication processors, streamlining data integration and network connectivity.

Key Features

High-Speed Ethernet Connectivity

• Supports 10Base-T and 100Base-TX Ethernet standards

• Auto-negotiation for seamless network speed adaptation

• RJ-45 copper interface for standard installations

Transient Data Capture

• Collects high-resolution dynamic and transient waveform data when paired with a Channel Enabling Disk

• Monitors machine startup and coast-down events for critical resonance and phase analysis

Integrated OK Relay

• Built-in relay with gold-plated contacts ensures reliable status signaling

• Rated 5A at 24 Vdc / 120 Vac, providing hardware alarm output to DCS or PLC systems

System Compatibility

• Fully compatible with 3500 M-series monitors (e.g., 3500/40M, 3500/42M, 3500/45M)

• Non-critical path module: failure does not affect core machine protection functions

Technical Specifications

Application Notes
The 146031-01 module is ideal for integrating 3500 Series racks with plant monitoring networks. For facilities requiring fiber optic connections or enhanced EMI resistance, the 146031-02 (100Base-FX) version is recommended.
