    The electrical parameters of intrinsic isolated barrier need to match field instrument/control room instrument electrical interface. Basically, we could complete the simple selection through the following 5 selection elements.


    Hazardous area signal

    Safe area signal

    Power supply

    Number of channels(Input channels/output channels)

    Install method

    Active 4-20mA

    Active 4-20mA

    Independentpower supply
