Description
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.
New Rack Installations
The same rack can contain both internal barrier and standard I/O module types without compromising the separation between hazardous and safe area field wiring.
The External Termination option is not available for I/O modules with internal barriers because hazardous area approvals do not allow the useof intrinsically safe wiring within a multi-cored cable assembly. Monitors that contain Triple Modular Redundant (TMR) rack options cannot use internal barrier I/O modules since connecting a transducer to multiple I/O module inputs will compromise the integrity of the IS system.
A rack that contains any internal barrier module must have a 3500/04-01 IS Earthing Module to provide the Barrier Module IS earth connection
