Functional Description

Bently nevada 135489-01 is a 3500/42, /70, /72 I/O Module with Internal Barriers (4 prox/accel channels) and Internal Terminations.3500 Internal Barriers are intrinsically safe interfaces that provide explosion protection for transducer systems connected directly to the 3500 Machinery Protection System. The internal barriers are fully compatible with the 3500 System and provide a convenient and cost-effective solution for installing all types of transducer systems within a hazardous area.

Unlike external barriers, 3500 Internal Barriers are an integral part of the 3500 System and will not degrade the system's performance.

Installation Guidelines

The internal barriers for a 3500 rack are incorporated in special Monitor I/O Modules. These barriers provide explosion protection for transducer systems that are connected to the 3500 system. An intrinsically safe (IS) earthing module provides the IS earth connection through the 3500 system backplane.

The IS Earth Module requires a dedicated I/O module position and precludes the use of this monitor position for other 3500 System modules. This limits a standard 19-inch rack to 13 monitor positions. Furthermore, a number of installation options are not available when internal barriers are installed in a 3500 rack.

I/O Module Positioning

Internal barrier I/O modules have an increased depth over that of standard barrier I/O modules. Consider the rack position with respect to adjacent modules to ensure that you can easily access the I/O modules during maintenance.

Internal barrier I/O and IS Earthing modules can occupy any general-purpose rack position and can be adjacent to standard I/O module types without compromising the 50 mm (2 in) physical separation requirement between safe and hazardous area field wiring.

Follow these guidelines when positioning I/O modules:

1. Group all internal barrier I/O modules in adjacent rack positions to simplify the installation

2. Place the IS Earthing Module in a rack position that provides easy access for routine online maintenance.

3. Consider the IS Earthing Module's positioning relative to adjacent internal barrier I/O modules and cabinet bulkheads.

If you plan to install standard I/O modules or the IS Earthing Module between a pair of internal barrier I/O modules, allow a minimum of two rack positions so that you can easily access the standard I/O or IS Earthing Module online without disturbing the adjacent I/O modules.
