The Bently Nevada 3500/90 is a high-performance communication gateway module designed to act as the primary information bridge between the 3500 machinery protection rack and external control systems. It provides extensive communication capabilities by collecting all rack-monitored values, alarms, and statuses from the backplane and transmitting them to distributed control systems, programmable logic controllers, or plant computers. By supporting standard industrial open protocols such as Modbus over both high-speed Ethernet TCP/IP and serial channels, this module ensures seamless integration with process control infrastructures.

Input Operating Voltage: Draws power directly from the 3500 rack backplane power supply (+5 Vdc and +24 Vdc).

Power Consumption: Low-power internal design, typically consuming 5.0 Watts (nominal) to 7.0 Watts (maximum).

Operating Temperature Range: -30 °C to +65 °C (-22 °F to +150 °F) for robust performance.

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

Relative Humidity Tolerance: 5% to 95% relative humidity, non-condensing.

Centralized Process Control Integration:

Remote Machinery Configuration:

SCADA and Data Acquisition Infrastructure:

Relaying all rack monitored values, alerts, and statuses to industrial plant DCS or PLC networks for automated process interlocks.

Enabling secure high-speed Ethernet communication paths with 3500 Rack Configuration Software for remote parameter updates and testing.

Interfacing seamlessly with plant-wide supervisory software or Data Acquisition Software packages via Modbus/TCP for historical logging.
