Product Introduction
The Bently Nevada 3500/92 (Part Number 125736-01) is a Communications Gateway Module for the 3500 Series machinery protection system. It serves as a data concentrator and protocol converter, enabling seamless integration of 3500 rack data with plant‑wide control systems, distributed control systems (DCS), programmable logic controllers (PLC), and condition monitoring software. The module collects dynamic and static data (vibration, position, temperature, speed, relay status) from all monitors in the 3500 rack via the internal backplane, and makes this data available over industry‑standard communication protocols. The 125736-01 variant typically includes Ethernet and serial interfaces with specific firmware options. The module occupies one half‑height slot in a 3500 rack and does not interfere with the protection functions of the monitor modules.

Application Scenarios
Integration with Plant DCS/PLC – Installed in 3500 racks at power plants, refineries, and chemical facilities to transmit vibration, temperature, and position data directly to a central control room, enabling operators to monitor machinery health alongside process variables.
Condition Monitoring Software Connectivity – Provides real‑time dynamic data (waveforms, orbits, trends) to Bently Nevada System 1™ or third‑party condition monitoring systems via Modbus or OPC, facilitating predictive maintenance and fault diagnosis.
Remote Access and Diagnostics – With Ethernet connectivity, the gateway allows engineers to remotely access 3500 rack data from an off‑site location, reducing the need for on‑site visits and enabling faster troubleshooting.
Data Archiving and Historian Integration – Feeds machinery data into plant historians (e.g., OSIsoft PI, Wonderware) for long‑term storage, compliance reporting, and performance analysis.
Alarm and Event Forwarding – Sends real‑time alert and danger statuses from 3500 monitor modules to control systems, allowing automated responses (e.g., audible alarms, DCS annunciation) without hardwiring each relay.
