Quick Detail

Description

The 128240-01 Proximitor/Seismic Monitor I/O Module is a four-channel module for Bently Nevada 3500 Series Racks that accepts inputs from proximity and seismic transducers. Each 128240-01 channel conditions signals for radial vibration (-3 dB 4 Hz to 4000 Hz or 1 Hz to 600 Hz ±1% accuracy), thrust position (-3 dB at 1.2 Hz), differential expansion (-3 dB at 0.41 Hz), acceleration, velocity, shaft absolute, eccentricity, and circular acceptance region. Operating at 23.9 V and 45.5 mA with 1.09 W power consumption, the 128240-01 fits one full-height rear slot. It functions in industrial environments from -30°C to +65°C and stores safely at -40°C to +85°C with 95% non-condensing humidity. Each 128240-01 Proximitor/Seismic Monitor I/O Module enables automated alarm configuration and precise machine monitoring, providing actionable data for predictive maintenance and vibration control in rotating machinery systems.

Applications

Monitor Radial Vibration Across Machinery

The 128240-01 Proximitor/Seismic Monitor I/O Module conditions radial vibration inputs using -3 dB direct filters from 4 Hz to 4000 Hz or 1 Hz to 600 Hz ±1% accuracy. Each 128240-01 channel calculates Smax from 0.125 to 15.8× running speed, providing automated vibration data for machinery control systems.

Measure Thrust Position and Differential Expansion

The 128240-01 processes thrust position signals with -3 dB direct filters at 1.2 Hz and gap filters at 0.41 Hz, achieving ±0.33% typical full-scale accuracy. Differential expansion measurements allow precise axial monitoring for rotating equipment in automation setups.

Capture Acceleration, Velocity, and Shaft Motion

Each 128240-01 channel measures acceleration, velocity, shaft absolute, eccentricity, and circular acceptance region with ±0.33% typical accuracy. The 128240-01 Proximitor/Seismic Monitor I/O Module supports 23.9 V supply, 45.5 mA current, and 1.09 W power, integrating into one full-height rear slot in 3500 Series Racks.

Operate in Industrial Temperature and Humidity Ranges

The 128240-01 functions from -30°C to +65°C and stores safely from -40°C to +85°C with 95% non-condensing humidity, enabling continuous automated monitoring in harsh industrial environments.

Specifications

Competitive Advantage

Simplify Installation and Rack Integration

The 128240-01 occupies one full-height rear slot, supports 23.9 V input and 1.09 W power, and integrates into 3500 Series Racks. The 128240-01 reduces wiring errors and allows quick installation of automated monitoring modules.

Enable User-Programmable Alarm Configuration

Each 128240-01 channel allows setting alert and danger thresholds for radial vibration, thrust, and velocity with ±0.33% typical full-scale accuracy. The 128240-01 Proximitor/Seismic Monitor I/O Module provides automated alarm triggering without manual intervention.

Maintain High Accuracy Across Frequency Filters

The 128240-01 preserves ±1% accuracy for radial vibration direct and gap filters, ±0.33% for 1X/2X vector filters, and ±5% maximum for Smax. This ensures precise vibration and position measurements for predictive maintenance in automated machinery systems.
