Detailed data
3500/40M 135489-04 Bently Nevada Proximitor I/O Module
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.
Note:Unlike external barriers, 3500 Internal Barriers are an integral part of the 3500 System and will not degrade the system's performance.
Installation Guide:
The internal barriers of the 3500 rack are incorporated into special monitor I/O modules.
These barriers provide explosion protection for sensor systems connected to the 3500 system. The Intrinsically Safe (IS) Grounding Module provides the IS ground connection through the 3500 system backplane.
The IS Grounding Module requires a dedicated I/O module position and prohibits the use of this monitor position for other 3500 system modules. This limits a standard 19-inch rack to 13 monitor positions. In addition, many mounting options are not available when the internal barriers are installed in a 3500 rack.
New Rack Installation:
The same rack can contain both internal barrier and standard I/O module types without compromising the isolation between hazardous and safe area field wiring.
The external termination option is not available for I/O modules with internal barriers because hazardous area certifications do not allow the use of intrinsically safe wiring in multi-conductor cable assemblies.
Monitors that contain the Triple Modular Redundant (TMR) rack option cannot use internal barrier I/O modules because connecting sensors to multiple I/O module inputs compromises the integrity of the IS system.
Racks containing any internal barrier modules must have a 3500/04-01 IS Grounding Module to provide the barrier module IS ground connection.
