1. Product Overview

The Bently Nevada 3500/92‑04‑01‑01 Communication Gateway Module 136180‑01 is a communication interface module designed for the Bently Nevada 3500 Machinery Protection System. Manufactured by Bently Nevada (a Baker Hughes company), this module enables reliable data exchange between the 3500 monitoring rack and external control systems such as DCS, PLC, or SCADA platforms.

The 3500/92 gateway collects real-time data—including vibration measurements, machine condition values, alarm statuses, and module diagnostics—from the 3500 rack and transmits them to plant automation networks via Ethernet or serial communications. This capability allows integration of machinery protection data into plant-wide monitoring systems, enabling predictive maintenance and centralized condition monitoring.
