3500/04 Internal Barriers Bently Nevada Asset Condition Monitoring 3500/04-01-00

3500/04 Internal Barriers are intrinsically safe interfaces that provide explosion
protection for transducer systems connected directly to the 3500 Machinery
Protection System.
The barrier designs 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 3500 System’s
performance.
We can supply most Bently Nevada transducer systems that have
comprehensive approvals for hazardous area installations and are matched to
those of the 3500 Internal Barriers (consult Table 1 for compatible monitors and
transducers). The design of each component complies both individually and as
part of a system with the strict safety requirements of North American and
International Standards. This removes the need for a system designer to
reference individual certificates to verify the compatibility between components.
Standard and Internal Barrier monitors can reside within the same 3500 rack,
which increases the overall flexibility of the 3500 system. Users can upgrade
standard monitors to those that contain internal barriers by replacing existing
I/O modules.

IS Earthing Module
Note: Order Internal Barriers by specifying the appropriate I/O
Module type for each monitor module, and install an IS Earthing
Module (p/n 3500/04-01) in each rack containing internal barriers.
Consult Specifications and Ordering Information for each 3500
monitor module to order the appropriate I/O module.
