Model KFD0 Galvanic Barrier

Brand: Dwyer Instruments, LLC
Does not ship to OH, United States
The Model KFD0 Loop Powered, Galvanic Barrier provides complete isolation for communication with Dwyer® intrinsically-safe transmitters approved for use in hazardous areas.

Galvanic barrier eliminates the need for a high integrity earth ground required when using shunt type diode type safety barriers. 

Unlike most other isolators, the Model KFD0-SCSEX1.55 does not require external power and has a low current draw. The housing is designed to easily mount on most standard DIN rails.
