Note：
Ui：the highest input voltage, the highest voltage which could work on transmitter
input terminals.
Uo：the highest output voltage, the highest voltage on intrinsically safe circuit
when safe barrier's output side is open.
Ii：the max. input current, the max. current which could work on transmitter input
terminals.
Io：the max. output current, the max. current on intrinsically safe circuit which
could be got from safe barrier output terminals.
Ci：the max. internal capacitance, the internal equal total capacitance which
could exist on transmitter input terminals.
Co：the max. external capacitance, the max. intrinsically safe capacitance which
