Konan Intrinsic Safety Solenoid Valves Explosion barrier SAF100-5

Intrinsic safety explosion barrier is an explosion-proof device with single channel, Zener-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.A-class ground is not necessary since the input and output are insulated
   each other.
3.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.
4.Despite in the hazardous location, conventional wiring is available.
5.Intrinsical proof of operational signal is figured out easily and at lower
   cost.
6.SAF100-5 safety barrier employ crimping terminal wiring method.
7.As SAF100-5 safety barrier has protection circuit, it will be not broken
   if you wired in the wrong polarity.
8.LED indicates the condition of the input and output
