Galvanic Barrier
Intrinsically Safe Isolators for Hazardous Locations
The MTL5041/5045 Galvanic Barrier provide total intrinsically safe
isolation for communication with Dwyer®pressure transmitters approved for
location in hazardous areas. Galvanic barrier eliminates the need for a high
integrity earth ground required when using shunt diode type safety barriers.
DIN rail mounting and plug-in signal and power connectors simplify installation
and maintenance
