Overview Details for MTL5541
Galvanic barrier
Series MTL5541 Galvanic Barrier
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.
Product Applications
- Electrically isolates pressure and level transmitters from unregulated circuits for intrinsically safe applications
- Easy snap-in installation for most DIN rails
- Safe to use in hazardous locations
