Product Overview

The Bently Nevada 3500/92-04-01-00 136188-02 is an Ethernet/RS485 Modbus I/O module. This module works as part of the 3500/92 Communication Gateway system. It fits into one full-height rear slot of the 3500 rack. The 3500/92-04-01-00 enables data exchange between the 3500 rack and external systems. You can use it with Modbus RTU or Modbus TCP protocols. This module is made in the U.S.A.

Technical Specifications

The 3500/92-04-01-00 136188-02 measures 241 mm x 24.4 mm x 99.1 mm. Its weight is only 0.44 kg. Power consumption depends on your I/O configuration. With Modbus RS232/RS422, it uses 5.0 watts typical. With Modbus RS485, it uses 5.6 watts typical.

The 3500/92-04-01-00 collects data through a high speed internal network. This data includes current measured values with time stamps. It also gathers module statuses and current alarm statuses. The exact data types depend on each module type. Channel configuration also affects returned data. The update time does not exceed 1 second for all rack modules.

Communication Protocols

The 3500/92-04-01-00 136188-02 supports several industrial protocols:

• BNC Host Protocol: For use with 3500 Configuration Software and 3500 Data Acquisition Software over Ethernet TCP/IP

• Modbus: Based on AEG Modicon PI-MBUS-300 Reference Manual, using RTU transmission mode

• Ethernet: 10 Mbps link conforming to IEEE802.3

• Protocol Stack: Ethernet TCP/IP frame and Modbus/TCP

• Connection: RJ-45 connector for 10BASE-T Ethernet cabling

Front Panel Indicators

The 3500/92-04-01-00 has two LED indicators:

• OK LED: Shows when the 3500/92-04-01-00 136188-02 is operating properly

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

Environmental Limits

The 3500/92-04-01-00 136188-02 operates in demanding conditions:

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