Product Overview

The Bently Nevada 3500/92-04-01-00 136180-01 is a communication gateway for the 3500 series. This module collects data from other modules inside the rack. It gathers current measured values with time stamps. The 3500/92 also retrieves module statuses and alarm statuses. All data moves through a high speed internal network. The exact data types depend on each module type. Channel configuration also affects what data you receive.

The 3500/92-04-01-00 136180-01 comes with an Ethernet/RS485 Modbus I/O module. It has low memory configuration (type 01). There is no agency approval option (type 00). This gateway is made in the U.S.A. It occupies one full-height front slot in the 3500 rack.

Technical Specifications

The 3500/92-04-01-00 has a main board measuring 241 mm x 24.4 mm x 242 mm. The I/O module measures 241 mm x 24.4 mm x 99.1 mm. Total weight is 1.26 kg. Power consumption is 5.0 watts typical with Modbus RS232/RS422 I/O. With the Modbus RS485 I/O module, power draw is 5.6 watts typical.

The data collection rate depends on your rack configuration. It will not exceed 1 second for all modules in the 3500 rack. This ensures timely data for your monitoring system.

Communication Protocols

The 3500/92-04-01-00 136180-01 supports multiple protocols. The BNC Host Protocol enables communication with 3500 Configuration Software. It also works with 3500 Data Acquisition and Display Software. This runs over Ethernet TCP/IP.

Modbus protocol follows the AEG Modicon PI-MBUS-300 Reference Manual. The gateway uses Remote Terminal Unit (RTU) transmission mode. For Ethernet, the link runs at 10 Mbps and conforms to IEEE802.3. The protocol supports Ethernet TCP/IP frame and Modbus/TCP. The connection uses an RJ-45 connector for 10BASE-T cabling.

Front Panel Indicators

The 3500/92 has two LED indicators on the front panel:

• OK LED: Shows when the 3500/92-04-01-00 is operating properly

• TX/RX LED: Indicates communication with other 3500 rack modules

Environmental Limits

The 3500/92-04-01-00 136180-01 operates in harsh industrial environments:

• Operating Temperature: -30°C to +65°C (-22°F to +149°F)

• Storage Temperature: -40°C to +85°C (-40°F to +185°F)

• Humidity: 95%, non-condensing

Installation Guidelines

Power down the 3500 rack before installing the 3500/92-04-01-00. Insert the main board into a full-height front slot. Mount the I/O module to the rear of the rack. Connect the RJ-45 cable to the Ethernet port. For RS485 connections, wire to the appropriate terminals. Configure the Modbus address using the software. Test communication with the 3500 Configuration Software. Verify data collection from all rack modules.
