Description

The Bently Nevada 140471-01 is a Prox/Velom I/O module designed for use with the 3500/42M Proximitor/Seismic Monitor system. This module serves as the physical interface between field-mounted transducers and the monitor signal conditioning circuitry within a 3500 rack. It features internal termination circuitry, eliminating the need for external termination blocks.

Features

4-channel input capability for proximity and seismic transducers.
Provides power, common, signal, and shield connections for each transducer channel.
Internal termination design for simplified field wiring.
Supports channel pair programming for monitoring functions such as radial vibration, thrust position, acceleration, or shaft absolute measurement.
Routes transducer signals to the main monitor module for alarm comparison and static value generation.
Includes recorder outputs and OK relay contacts for system status monitoring.

Applications

Upstream Production Platforms: Protection for offshore/FPSO pumps, compressors, and turbines.
Refineries: Monitoring of FCCU/H2 compressors and crude pumps.
LNG Plants: Safeguarding refrigeration and methane compressors.
Power Generation: Protection for turbines, generators, and boiler feed pumps.
Hydroelectric Facilities: Monitoring of low-speed alignment and thrust for hydro-turbines.

Installation Guidelines

Ensure the 3500 rack power supply is de-energized before inserting or removing any module to prevent damage from transient voltages.
Locate the I/O slot at the rear of the 3500 rack that corresponds to the front-mounted 3500/42M monitor module.
Align the top and bottom edges of the 140471-01 module with the rack guide rails.
Slide the module into the slot until the connectors are fully seated against the backplane.
Verify that all field wiring is properly secured to the internal terminals according to the system wiring diagram.

FAQs
