Quick Detail

Description

The 128229-01 Proximitor Seismic I/O Module is designed for Bently Nevada 3500 Series Racks, providing four channels for proximity and seismic transducers. Each 128229-01 channel conditions signals for radial vibration, thrust position, acceleration, differential expansion, shaft absolute, eccentricity, and velocity, with user-programmable alarms. Operating at 23.9 V and 45.5 mA, the 128229-01 consumes 1.09 W and fits one full-height rear slot. It functions in industrial temperatures from -30°C to +65°C, with storage up to -40°C to +85°C and 95% non-condensing humidity. Radial vibration filters on the 128229-01 cover -3 dB from 4 Hz to 4000 Hz or 1 Hz to 600 Hz with ±1% accuracy, while thrust and differential measurements achieve ±0.33% typical accuracy. The 128229-01 Proximitor Seismic I/O Module enables precise vibration and position monitoring, delivering actionable machine data for automation and predictive maintenance systems.

Applications

Monitor Radial Vibration and Shaft Motion

The 128229-01 Proximitor Seismic I/O Module conditions input from proximity and seismic transducers to measure radial vibration across -3 dB 4 Hz to 4000 Hz or 1 Hz to 600 Hz ±1% accuracy. Each 128229-01 channel calculates Smax from 0.125 to 15.8× running speed and provides actionable vibration data for machinery automation.

Measure Thrust Position and Differential Expansion

The 128229-01 processes thrust and differential expansion signals using a -3 dB direct filter at 1.2 Hz and a gap filter at 0.41 Hz, achieving ±0.33% full-scale typical accuracy. This allows precise axial displacement and expansion monitoring for rotating equipment.

Record Acceleration and Velocity for Machine Protection

Each 128229-01 channel measures acceleration and velocity with ±0.33% accuracy, reporting to operators for automated alerting. Operating at 23.9 V and 45.5 mA, consuming 1.09 W, the 128229-01 fits one full-height rear slot in 3500 racks, enabling integration into existing automation systems.

Enable High-Temperature and Humidity Operation

The 128229-01 Proximitor Seismic I/O Module functions from -30°C to +65°C with storage from -40°C to +85°C and 95% non-condensing humidity, supporting industrial environments for continuous vibration and position monitoring.

Specifications

Competitive Advantage

Deliver Accurate Multi-Channel Monitoring

The 128229-01 provides four channels for proximity and seismic inputs, measuring radial vibration (-3 dB 4 Hz to 4000 Hz or 1 Hz to 600 Hz ±1% accuracy), Smax from 0.125 to 15.8× running speed, shaft absolute, eccentricity, and circular acceptance region. Each 128229-01 channel ensures precise data for automation monitoring and alarms.

Reduce Wiring Errors with Rack Integration

The 128229-01 occupies one full-height rear slot in Bently Nevada 3500 Series Racks, supporting 23.9 V supply and 1.09 W power consumption at 45.5 mA. The 128229-01 integrates directly into rack wiring, reducing setup time and ensuring correct signal routing for all four channels.

Support Precise Alarm Configuration

Each 128229-01 channel allows user-programmable alert and danger setpoints for radial vibration, thrust, differential expansion, acceleration, and velocity. The 128229-01 Proximitor Seismic I/O Module provides ±0.33% typical full-scale accuracy and ±1% maximum for thrust and differential expansion, enabling reliable automated machine alerts.

Maintain Signal Accuracy Across Frequency Range

The 128229-01 preserves ±1% accuracy for radial vibration gap and direct filters, ±0.33% typical accuracy for 1X/2X vector filters, and ±5% maximum for Smax calculations. The 128229-01 supports industrial temperatures from -30°C to +65°C and storage from -40°C to +85°C at 95% non-condensing humidity, ensuring consistent monitoring under harsh conditions.
