Brand: Bently Nevada
Series / Family: 3500 Machinery Protection / Monitoring System
Model / Part Number: 3500/02 — 129133‑02
Type: System architecture & rack configuration / interface / module in 3500 system
Role: This unit is part of the 3500 rack architecture; it helps define the system’s modular layout and configuration logic
The 3500/02 (129133‑02) is a core module of the 3500 monitoring and protection system for rotating machinery. It supports system architecture, rack configuration, and intermodule communication in the 3500 family. The 3500 system is a widely used machinery protection platform that detects vibration, speed, and other critical parameters in real time, helping protect equipment from failure.
This module plays a role in defining how rack components communicate, managing configuration logic, and establishing the backbone for the protection system. It is essential for arranging modules such as power supplies, monitor modules, relay modules, I/O modules, and communication gates into a coherent rack architecture.
The 3500 system as a whole is designed for continuous, online monitoring, with modular flexibility to tailor to different machine types, redundancy levels, and environmental conditions.
