Intrinsically safe zener barrier.

SERIES MTL7706/7787 ZENER BARRIER

Intrinsically Safe Barriers for Hazardous Locations

The MTL7706/7787 is an intrinsically safe (IS) shunt-diode barrier that can be used to communicate with and provide isolations for certain Dwyer® transmitters approved for use in hazardous areas. These barriers limit the amount of energy allowed to pass into the hazardous area, which inhibit ignition in flammable atmospheres.

Product Applications

Electrically isolates pressure and level transmitters from unregulated circuits for intrinsically safe applications

Approved for use in hazardous areas
