The Bently Nevada 3500/92-04-01-00 (also 136180-01) acts as a central data hub in the 3500 monitoring system. It gathers real-time measurement values, module statuses, and alarm conditions via a high-speed internal network. This gateway then shares that data through standard industrial protocols.
Specifically, this model comes with the 04 I/O Module, which supports both Ethernet and RS485 Modbus. It also includes the 01 Low Memory option and no agency approvals (00). You can use it to connect your 3500 rack to host software or a Modbus network.
The 3500/92-04-01-00 uses two main protocols.
BNC Host Protocol: Works with 3500 Configuration Software and Data Acquisition software over Ethernet TCP/IP.
Modbus: Based on the AEG Modicon PI-MBUS-300 reference. It uses the Remote Terminal Unit (RTU) transmission mode.
Additionally, it supports Modbus/TCP over Ethernet.
Speed: 10 Mbps, conforming to IEEE802.3.
Connection: RJ-45 (telephone jack style) for 10BASE-T cabling.
Frame Type: Ethernet TCP/IP.
Data types: Current measured values with time stamps, module statuses, current alarm statuses.
Update time: ≤ 1 second for all modules in the rack, depending on configuration.
Internal network: High-speed communication with other 3500 modules.
OK LED: Lights up when the gateway operates correctly.
TX/RX LED: Shows active communication with other modules in the 3500 rack.
With Modbus RS232/RS422 I/O Module: 5.0 Watts typical.
With Modbus RS485 I/O Module: 5.6 Watts typical.
Operating temperature: -30°C to +65°C (-22°F to +149°F) for both main and I/O modules.
Storage temperature: -40°C to +85°C (-40°F to +185°F).
Humidity: 95% non-condensing.
Height x Width x Depth: 241 mm x 24.4 mm x 242 mm (9.50 in x 0.96 in x 9.52 in).
Weight: 0.82 kg (1.8 lb).
Height x Width x Depth: 241 mm x 24.4 mm x 99.1 mm.
The 3500/92 occupies 1 full-height front slot in the 3500 rack.
Follow these steps for a successful installation.
Power down the 3500 rack before inserting the gateway.
Insert the main board into a full-height front slot. Push firmly until seated.
Attach the selected I/O module (already configured as 04 type for Ethernet/RS485).
Connect the Ethernet cable to the RJ-45 port for network access.
For RS485 connections, use the appropriate Modbus terminal wiring.
Re-apply power and check the OK LED turns green.
Configure the gateway using the 3500 Configuration Software.
Meanwhile, ensure the operating temperature stays within -30°C to +65°C. Also keep humidity below 95% non-condensing.

1. Can the 3500/92-04-01-00 replace older 3500/92 models?
Yes, it is backward compatible with most 3500 racks. However, check your firmware version. The 3500/92-04-01-00 requires compatible rack firmware for full Modbus functions.
2. Does this gateway support both Ethernet and RS485 at the same time?
Yes, the 04 I/O Module allows concurrent operation. You can use Ethernet for configuration software and RS485 for Modbus RTU simultaneously.
3. What happens if the OK LED is off?
First, check power supply to the rack. Next, reseat the module. If the light stays off, the internal power circuit may have failed. Contact technical support.
4. How fast does it update data for all channels?
The update time will not exceed 1 second for all modules in the 3500 rack. Most configurations update much faster, typically within 200-500 ms.
5. Is the Bently Nevada 3500/92-04-01-00 suitable for offshore environments?
Yes, it holds DNV GL and ABS marine certifications. It meets rules for ships and offshore units, making it reliable for harsh marine conditions.
