MTL Instruments barriers are intrinsically safe “shunt diode” safety barriers. They are passive network devices that use Zener diodes, resistors, and fuses to safely divert excess electrical energy to ground and thus prevent sparking in or overheating of equipment in hazardous areas. Key benefits of MTL Instruments barriers are low cost and the ability to operate with data in analog DC or high-speed digital forms.

Model MTL7728+ 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 MTL7728+ is certified 'ia' for all zones and 'IIC' for all explosive atmospheres.
