Purpose-Built Velocity Transducer Interface

The 170180-02-05 is specifically configured for two-wire velocity transducers. This dedicated interface helps avoid the compatibility issues that may arise when using an incorrect sensor I/O variant.

FieldMonitor System Integration

Designed for the Bently Nevada FieldMonitor 1701 platform, the module occupies one slot in a compatible terminal base and works with the associated monitoring hardware.

Introduction

The Bently Nevada 170180-02-05 External Sensor I/O Module is a dual-channel external transducer interface designed for the FieldMonitor machinery condition monitoring system. It connects two compatible two-wire velocity transducers to the corresponding monitoring hardware, allowing vibration signals to be incorporated into machinery condition assessment.

Unlike a general-purpose sensor interface, this model has a dedicated two-wire velocity transducer configuration. Both Channel A and Channel B support compatible velocity transducers, making it suitable for installations requiring vibration measurements at two separate monitoring points.

The module occupies one slot in a compatible FieldMonitor terminal base. It is commonly associated with the 1701/25 Seismic Input Monitor configuration.

For industrial maintenance teams, purchasing the correct 170180 variant is particularly important. Models within the same product family can support different sensor technologies, so the complete part number should be verified before ordering.

With its compact construction and dedicated dual-channel interface, the 170180-02-05 is a practical component for maintaining existing Bently Nevada FieldMonitor installations.
