Overview

The Bently Nevada 128229-01 Proximity/Seismic I/O Module is part of the 3500 Series Machinery Protection System from GE’s Bently Nevada division. This module is essential for monitoring vibration, shaft position, and structural integrity of rotating machinery like turbines, compressors, and motors.

It supports four input channels, each capable of receiving signals from proximity probes or seismic transducers. These inputs are processed to detect abnormal conditions such as misalignment, imbalance, or bearing wear. The module’s internal terminations simplify installation and reduce wiring complexity, streamlining the integration process.

Additionally, the 128229-01 provides high-speed data acquisition, enabling real-time diagnostics and seamless integration with plant-wide monitoring systems. It is commonly used in industries like oil & gas, power generation, and process industries, where ensuring equipment uptime and implementing predictive maintenance is critical.
