Description
Overview
The Bently Nevada 3500/91-01-02-02 is a dual-port fiber Ethernet communication gateway designed for the 3500 Machinery Protection System. It provides deterministic Ethernet Global Data (EGD) connectivity between the 3500 monitoring rack and external control platforms including GE Mark VI/VIe turbine controllers, DCS, and SCADA systems.
This module is engineered for high-integrity, real-time data transfer in redundant or dual-network architectures. It enables continuous transmission of machine protection data, including vibration measurements, process variables, alarm conditions, and system diagnostics, over industrial fiber-optic networks.
The unit is installed in one front slot and one rear I/O slot within the 3500 rack assembly.
