Product Overview

The Bently Nevada 86497-01-02-02-00 is an interface module used within the 3500 machinery protection platform to support signal routing and integration between transducer inputs and plant monitoring/control layers. Installed in a 3500 rack architecture, this module assists with structured I/O handling for vibration-related channels when used with appropriate 3500 I/O modules (such as Prox/Velom and vibration/accelerometer interfaces). It is typically applied in rotating equipment protection schemes where consistent signal handling, configuration control, and alarm functionality are required.

This part is listed as discontinued (end-of-life), which makes verification of rack compatibility and spares strategy important for maintenance teams supporting existing installations.

Operational Use Cases

• Integration support for 3500 racks monitoring turbines, compressors, pumps, and other critical rotating equipment

• Plant interface and signal organization in machinery protection systems where multiple vibration channels must be managed consistently

• Aeroderivative gas turbine and compressor trains requiring stable vibration measurement paths and alarm-ready architectures

• Maintenance replacement in existing 3500 installations where the same module revision is required for configuration continuity
