Product Description

Overview

The Bently Nevada 133396-01 is a 4-Channel Vibration Monitor I/O Module with internal terminations, engineered for use with the 3500/42M Proximitor Seismic Monitor in the 3500 Series Machinery Protection System. Designed for rear-mount installation, this module provides a direct connection for field-mounted vibration sensors, enabling accurate vibration monitoring and diagnostic analysis without the need for external terminal blocks.

Its integrated screw-terminal blocks allow field wiring to be connected directly to the back of the 3500 rack, optimizing cabinet space and simplifying installation.

Key Features

High-Fidelity Signal Transmission

• Maintains signal integrity for low-voltage vibration inputs

• Supports dynamic vibration waveforms from Proximitor®, accelerometer, or velocity sensors

• Minimizes electromagnetic interference (EMI) for precise System 1 diagnostics

Versatile Sensor Compatibility

• Works with Proximitor® sensors for radial vibration, thrust position, and REBAM® measurements

• Supports seismic transducers including piezo-velocity and accelerometers

• Supplies stable -24 Vdc power directly to connected sensors

Self-Diagnostics and Reliability

• Monitors the integrity of connected sensors and wiring

• Triggers a “NOT OK” status if sensor or wiring faults occur

• Supports 4 independent channels with continuous status verification

Environmental and Mechanical Durability

• Operating Temperature: -30°C to +65°C (-22°F to +150°F)

• Humidity Tolerance: Up to 95% non-condensing

• Designed to withstand industrial vibration and mechanical shock typical in turbine and compressor environments

Technical Specifications

Applications

The 133396-01 is ideal for critical machinery monitoring where precise vibration measurement is required:

FAQ

Q: What is the purpose of the 133396-01 module?
A: It routes vibration signals from Proximitor® and seismic sensors to the 3500/42M monitor, providing accurate real-time vibration monitoring.

Q: Can it be used in limited cabinet space?
A: Yes, internal terminations eliminate the need for external terminal strips, saving space.

Q: How does it handle sensor or wiring faults?
A: Built-in self-diagnostics continuously monitor the sensors and wiring. A fault triggers a “NOT OK” status on the 3500/42M monitor.

Q: What type of sensors are supported?
A: Compatible with Proximitor® radial vibration probes, thrust position sensors, REBAM® sensors, and piezo-velocity accelerometers.

Q: What is the module’s operating temperature range?
A: -30°C to +65°C (-22°F to +150°F).
