Quick Detail

Description

The 140471-01 Prox/Velom I/O Module is a four-channel Prox/Accel Velomitor designed for industrial automation applications. Each channel accepts input from proximity and seismic transducers, conditioning signals to provide precise radial vibration, thrust, differential expansion, acceleration, shaft absolute, and velocity measurements. The module operates at a supply voltage of 23.9 V, supply current of 45.5 mA, and typical power consumption of 1.09 W. It supports a wide operating temperature range: -30°C to +65°C (-22°F to +150°F) with Internal/External Termination I/O modules, and 0°C to +65°C (32°F to +150°F) with Internal Barrier I/O modules, with storage temperatures from -40°C to +85°C (-40°F to +185°F) and humidity up to 95% non-condensing. Radial vibration measurements feature user-programmable direct filters from 4 Hz to 4000 Hz or 1 Hz to 600 Hz with ±1% accuracy, gap filters at -3 dB/0.09 Hz, and Smax tracking from 0.125× to 15.8× machine speed. The 140471-01 allows configuration of alert and danger setpoints via 3500 Rack Configuration Software, enabling real-time machine protection and automated operational reporting.

Applications

Monitor Radial Vibration in Turbomachinery

The 140471-01 accepts proximity and seismic transducer inputs, measuring radial vibration with direct filter user-programmable from 4 Hz to 4000 Hz or 1 Hz to 600 Hz with ±1% accuracy, and gap filter -3 dB at 0.09 Hz. Use this data to detect shaft movement and vibration in pumps, compressors, and turbines.

Track Thrust and Differential Expansion

Configure the 140471-01 via 3500 Rack Configuration Software to monitor thrust position and differential expansion. Accuracy is ±0.33% full-scale typical, ±1% maximum, with Smax range 0.125× to 15.8× running speed. This enables precise measurement of axial movements for rotating machinery.

Measure Shaft Absolute and Velocity

With 1X and 2X vector filters and Smax tracking, the 140471-01 provides real-time shaft absolute position and velocity readings. This helps operations staff adjust machine speed and detect misalignment or wear in bearings.

Detect REBAM and Acceleration Events

The 140471-01 conditions signals for REBAM and acceleration, ensuring machinery protection by comparing measured values to user-programmed alert and danger setpoints in real time.

Specifications

Competitive Advantage

Wide Operational Temperature Range

The 140471-01 operates from -30°C to +65°C (-22°F to +150°F) with Internal/External Termination I/O Modules, and 0°C to +65°C (32°F to +150°F) with Internal Barrier I/O Modules. Storage range is -40°C to +85°C (-40°F to +185°F). This allows deployment in extreme industrial environments.

Low Power Consumption

Typical power draw is only 1.09 W at 23.9 V and 45.5 mA, minimizing energy use while providing continuous monitoring.

High-Accuracy Measurements

Radial vibration and thrust measurements maintain ±1% accuracy, gap filters at -3 dB, and Smax monitoring from 0.125× to 15.8× machine speed, giving precise actionable data for automation systems.

Real-Time Machine Protection

Using 3500 Rack Configuration Software, the 140471-01 allows configuration of alert and danger setpoints for each channel. Operators and maintenance personnel receive instant notifications of deviations in radial vibration, thrust, differential expansion, and acceleration, enabling automated protective actions.
