MTL 7700 Intrinsically Safe Barrier

The MTL7700 Intrinsically Safe Barriers are 1- or 2-channel DIN-rail mounted shunt-diode safety barriers that use intrinsically safe explosion-protection techniques to pass electrical signals between safe and hazardous areas, while limiting transferred energy to a level that cannot ignite flammable atmospheres. Connected in series with wiring entering any hazardous area on process plant, MTL7700 Series barriers prevent explosions in all normally occurring explosive atmospheres – including mixtures of air with flammable gases, vapors, dusts and fibers – if a fault or faults develop in the safe area.

The 1- or 2-channel E+H RN22 active barrier powers analog instrument loops and safety instrumented systems up to SIL 2 (SC 3). The intrinsically safe, HART® transparent interface establishes a link between field devices and process control. It interfaces with 2-/4-wire devices in hazardous areas and provides a second galvanically isolated signal output acc. to NAMUR NE 175. This opens a second channel for the process optimization domain without affecting the traditional automation system. No manual hardware settings are required at the device for commissioning.
