Overview
The Bently Nevada 289837-01 Proximitor/Seismic I/O Module provides precise vibration and position measurements for industrial machinery. Moreover, it supports four configurable channels, each compatible with proximity, velocity, or acceleration transducers. Users can define alarm thresholds, measurement types, and signal conditioning through 3500 Rack Configuration Software.
Functional Highlights
- Multi-Measurement Capability: Supports radial vibration, thrust, eccentricity, differential expansion, acceleration, and velocity.
- Configurable Alarm Setpoints: Users can set Alert and Danger thresholds from 0–100% full-scale.
- LED Indicators: OK, ALERT, DANGER, and Bypass LEDs provide instant operational feedback.
- Buffered Outputs: Each channel features coaxial connectors with 499 Ω output impedance and short-circuit protection.
