Description of MTL7787+ Zener-Diode Barrier MTL7787+ Safety Barriers Arrived

Model MTL7787+ is an intrinsically safe, zone-powered, Zener-diode barrier for use in conventional fire detection systems for protection within hazardous areas.

Each Zone contains two stages of pulse-tested Zener or forward- connected diodes and an 'infallible' terminating resistor. In the event of an electrical fault in the safe area, the diodes limit the voltage that can reach the hazardous area and the resistor limits the current. A fuse protects the diodes, and the two stages of voltage limitation ensure continued safety if either stage should fail. No active output-current limiting circuits are employed.

Model MTL7787+ is certified 'ia' for all zones and 'IIC' for all explosive atmospheres.

Overview of 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.

Bussed Power applications and connections  MTL7787+ Zener-Diode Barrier MTL7787+ Safety Barriers Arrived

When a number of barriers use a common power supply, the optional power link (BPL7700) can be used. Typical applications

include hazardous-area switches, solenoids and 4–20mA transmitters; and the barriers it can be used with are the MTL7706,

MTL7707+, MTL7787+, MTL7787P+ and MTL774x. 

MTL7787+ Zener-Diode Barrier MTL7787+ Safety Barriers Arrived

Zener diodes and ordinary silicon diodes have a typical forward voltage drop of approximately 0.6V/diode. Diode return paths with Schottky diodes have a typical voltage drop of <0.3V for each diode in the chain, eg, MTL7787+, 7787P+.
