DWYER USA ABS Galvanic Barrier, Color : BLUE

galvanic barrier

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
