Name: BENTLY 3500-20 Rack Interface Module | Qiming Automation
Brand: Bently Nevada

Description

The Bently 3500-20 acts as the nerve center for data flow within the 3500 Machinery Protection System. It is designed to be installed directly into the 3500 rack, where it interfaces with up to 16 I/O modules via the rack’s backplane. This module is responsible for conditioning and digitizing the analog signals received from sensors, converting them into a format that can be easily processed by the system’s central processing unit (such as the 3500-05 module).

3500-20

One of its standout features is its support for multiple communication protocols, including MODBUS RTU, Ethernet/IP, and Profibus. This versatility allows it to integrate seamlessly with a wide range of existing control systems and software platforms, facilitating the transfer of critical machinery health data to operators and maintenance teams, whether they are on-site or remotely. The 3500-20 also incorporates advanced diagnostic capabilities, constantly monitoring its own operation and the integrity of the data it processes. In the event of a communication failure, signal anomaly, or internal issue, it can quickly alert the system, enabling rapid troubleshooting and minimizing downtime.

In terms of system architecture, the 3500-20 works in tandem with other modules in the 3500 series. For example, it can feed processed data to the 3500-05 central processing module for in-depth analysis, and then communicate the results to display modules (like the 3500/42M) for visual representation. Its modular design allows for easy expansion and customization of the monitoring system, enabling users to add or remove I/O modules as per their specific machinery monitoring requirements.
