Dwyer MTL5541 Series Galvanic Barrier
BENEFITS/FEATURES
- Easy snap-in installation for most DIN rails
- Safe to use in hazardous locations
APPLICATIONS
Electrically isolates pressure and level transmitters from unregulated circuits for intrinsically safe applications
DESCRIPTION
The Series MTL5541 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.
