  • Konan Intrinsic Safety Solenoid Valves Explosion Barrier Saf3 5 Mtl728 - China

    price: contact company for price

    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

    Â Â the circuit and components in hazardous area from being affected by

    Â Â 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

    Â Â cost.

    5As SAF3- 5 safety barrier has protection circuit, it will be not broken

    Â Â if you wired in the wrong polarity.

    6SAF3- 5 safety barrier employ crimping terminal wiring method.

    Model code SA F3- 5 MTL728+
