3500/15 106M1079-01 15-slot system frame

The 3500/15 106M1079-01 is a 15-slot system frame developed by Bently Nevada, serving as the core hardware carrier and backplane communication hub of the 3500 Series machinery protection system. It provides mechanical installation space, power distribution, and data transmission interfaces for various 3500-series monitor modules (e.g., vibration monitors, position monitors) and auxiliary modules, ensuring the coordinated operation of the entire protection system. Below is its detailed information:

1. Basic Information

Brand: Bently Nevada
Model: 3500/15
Part Number: 106M1079-01
Product Type: 15-slot Backplane Frame (for 3500 Series Machinery Protection System)
Core Role: Integrates module installation, power supply distribution, and inter-module communication; acts as the "hardware backbone" of the 3500 system.

2. Core Functional Features

As the foundational component of the 3500 system, its design focuses on reliability, expandability, and ease of maintenance, with the following key functions:

15-Slot Module Capacity: Provides 15 standard slots (compatible with all half-height and full-height 3500-series modules) to accommodate monitor modules (e.g., 3500/33, 3500/42M), communication modules (e.g., 3500/92), and power modules. This flexible slot design allows users to configure the system based on actual monitoring needs (e.g., number of machinery axes, monitored parameters).
Unified Power Distribution: Integrates a built-in power distribution circuit to convert the external input power into stable DC power (matching the voltage requirements of 3500 modules) and distribute it uniformly to all installed modules. It also includes overcurrent and overvoltage protection to prevent module damage from power fluctuations.
Backplane Communication Bus: Embeds a high-speed internal communication bus (compliant with Bently Nevada’s proprietary protocol) that enables real-time data transmission between modules (e.g., keyphasor signals from 3500/25 to vibration monitors) and between the frame and upper computer (via communication modules). The bus ensures low-latency data interaction, critical for real-time protection of rotating machinery.
Status Monitoring & Fault Alert: Equipped with a system-level status indicator (e.g., "Power OK," "Bus OK") on the front panel. If anomalies occur (e.g., power failure, bus communication interruption), the indicator triggers a visual alert to help maintenance personnel quickly locate system-level faults.
Mechanical Protection & EMC Compliance: Adopts a rugged metal enclosure with anti-electromagnetic interference (EMI) design, complying with industrial EMC standards (e.g., IEC 61000-6-2). This prevents external electromagnetic noise (from motors, inverters, etc.) from interfering with internal module communication and ensures stable operation in harsh industrial environments.
