Quick Detail

Description

The Bently Nevada 133442-01 I/O Module is a 2-channel tachometer designed for industrial automation. The 133442-01 I/O Module accepts input from proximity probes or magnetic pickups, measuring shaft speed, rotor acceleration, and rotation direction. Configurable via 3500 Rack software, it supports speed setpoint alarming, zero-speed notification, rotor acceleration alarming, and reverse rotation alerts. The 133442-01 I/O Module supplies conditioned Keyphasor signals to the 3500 rack backplane, eliminating the need for a separate module. Inputs range from +10 V to -24 V, with 20 kΩ standard impedance, and it powers transducers at 24 Vdc, 40 mA max. Buffered outputs are provided via Euro-style connectors, and recorder outputs deliver 4–20 mA proportional signals. Rack space required is 1 full-height front slot for the monitor and 1 rear slot for the I/O module.

Applications

Shaft Speed Monitoring
The Bently Nevada 133442-01 I/O Module measures shaft speed using proximity probes or magnetic pickups with an input range of +10 V to -24 V and 20 kΩ impedance. The 133442-01 I/O Module updates measurements every 100 ms, enabling precise rpm tracking for turbines, compressors, and pumps in automated monitoring systems.

Rotor Acceleration Detection
The Bently Nevada 133442-01 I/O Module calculates rotor acceleration and triggers alarms when user-programmed thresholds are exceeded. With a 0.3662 µA per bit resolution in 4–20 mA recorder outputs, the 133442-01 I/O Module provides accurate data for predictive maintenance planning.

Keyphasor Signal Distribution
The Bently Nevada 133442-01 I/O Module outputs conditioned Keyphasor signals via coaxial connectors with 550 Ω impedance. This allows the 133442-01 I/O Module to supply other 3500 rack modules without separate Keyphasor devices, streamlining automation signal flow.

Recorder Output Integration
The Bently Nevada 133442-01 I/O Module provides 4–20 mA recorder outputs with voltage compliance of 0–12 V and load resistance up to 600 Ω. The 133442-01 I/O Module feeds proportional speed or acceleration data into process control systems for automated monitoring.

Specifications

Competitive Advantage

Direct Shaft Monitoring
The Bently Nevada 133442-01 I/O Module directly accepts 1–2 transducer signals with input impedances from 7.15 kΩ to 40 kΩ, delivering precise shaft speed and direction data. The 133442-01 I/O Module eliminates the need for signal conversion, simplifying industrial automation integration.

Configurable Alarm Options
The Bently Nevada 133442-01 I/O Module allows alarms for speed setpoints, zero-speed, rotor acceleration, and reverse rotation. The 133442-01 I/O Module generates alerts in real-time, leveraging its 100 ms update rate to respond immediately to abnormal conditions.

Peak Value Storage
The Bently Nevada 133442-01 I/O Module stores maximum speed, reverse speed, and rotation counts, which can be reset by operators. Using its high-resolution 4–20 mA outputs, the 133442-01 I/O Module provides quantitative peak data for maintenance evaluation.

Low Power and Transducer Support
Operating at 5.8 W and supplying 24 Vdc, 40 mA per channel, the Bently Nevada 133442-01 I/O Module powers up to two transducers simultaneously. The 133442-01 I/O Module supports automation setups without additional power modifications.

Easy Rack Installation
The Bently Nevada 133442-01 I/O Module requires 1 full-height front slot for the monitor and 1 rear slot for the I/O module. The 133442-01 I/O Module simplifies rack integration, reducing installation time while providing complete shaft monitoring functionality.
