Series MTL5041/5045 Galvanic Barrier

Brand: Dwyer Instruments, LLC

The Series MTL5041/5045 Galvanic Barrier provides intrinsically safe isolation for communication with Dwyer® transmitters approved for use in hazardous areas.

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

DIN rail mounting and plug-in signal and power connectors simplify installation and maintenance.
