Model KFD0 Galvanic Barrier

Loop Powered, Intrinsically Safe Isolators

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.

Product Applications

  • Used to isolate voltages for intrinsically safe applications for HHT series
