Bently Nevada 3500/92-04-01-01 Communication Gateway Module

Product Overview

The Bently Nevada 3500/92-04-01-01 Communication Gateway Module is a communication interface module used in the 3500 Machinery Condition Monitoring System. It provides network access to all monitored values and statuses from the 3500 rack, allowing integration with DCS, PLC, SCADA, and plant monitoring systems through Ethernet and serial communication interfaces.

The module acts as a data bridge between the Bently Nevada vibration monitoring rack and higher-level control systems, transmitting real-time machine condition data such as vibration values, alarm status, and module health information.
