Series MTL5541 Galvanic Barrier

Intrinsically Safe Isolators for Hazardous Locations

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
