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

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.
