Konan Intrinsic Safety Solenoid Valves Explosion barrier SAF3-5 , MTL728+

Intrinsic safety explosion barrier is an explosion-proof device with single channel, shunt-diode DC circuit that enables interactive electric signaling without short circuit while controlling energy transmission in order to prevent ignition in explosive atmosphere.
1.Applicable to Zone 0.
2.When serially connected to a transmission circuit, the barrier protects
   the circuit and components in hazardous area from being affected by
   a serious accident in the non-hazardous area.
3.Despite in the hazardous location, conventional wiring is available.
4.Intrinsical proof of operational signal is figured out easily and at lower
   cost.
5.As SAF3-5 safety barrier has protection circuit, it will be not broken
   if you wired in the wrong polarity.
6.SAF3-5 safety barrier employ crimping terminal wiring method.
