Bently Nevada 3500/91-01-01-00 EGD Communication Gateway | 3500 Series

Product Overview

The Bently Nevada 3500/91-01-01-00 serves as a specialized communication bridge designed to export 3500 rack data using the Ethernet Global Data (EGD) protocol. This module enables high-speed, deterministic data transfer between the machinery protection system and GE control systems or other EGD-compatible networks. By centralizing all monitor data into a single Ethernet output, it provides real-time visibility into machine health across the plant network. We guarantee this unit is 100% brand new and original factory equipment.

Engineering Advantages

The 3500/91-01-01-00 optimizes industrial data workflows through several engineering-focused features:

• High-Speed Data Throughput: Unlike standard Modbus gateways, the EGD protocol allows this module to broadcast "pages" of data deterministically. This ensures your control system receives vibration and position updates at precise intervals without network jitter.

• Space-Efficient Design: The module occupies a single slot in the 3500 rack. Its compact 1.9 cm width allows engineers to maximize rack density for other critical monitoring cards.

• Simplified Network Topology: This gateway replaces the need for multiple analog outputs by converting all internal rack data into a single digital Ethernet stream. This significantly reduces copper wiring costs and installation time.

• USA-Engineered Resilience: Bently Nevada constructs this module in the USA using industrial-grade components that withstand the high-vibration and high-heat environments common in turbine decks and compressor sheds.

FAQs

• Does this module support Modbus TCP/IP?

  No, the 3500/91 utilizes the Ethernet Global Data (EGD) protocol specifically. If your system requires Modbus, we recommend the 3500/92 or 3500/90 modules instead.

• Is the 3500/91-01-01-00 compatible with older 3500 racks?

  Yes, this module works with all standard 3500 racks. However, you must verify that your Rack Interface Module (RIM) firmware supports the EGD gateway functions for seamless data mapping.

• How do I configure the EGD data pages?

  You configure the data transmission parameters using the Bently Nevada 3500 Rack Configuration Software. This allows you to select which specific monitor values the gateway broadcasts to the network.

• What is included in the "Brand New" packaging?

  Each 3500/91-01-01-00 arrives in its original factory-sealed box, including the primary monitor module and the corresponding rear I/O module, backed by a full 1-year warranty.
