In the “Standard Specifications” section in the ITV series catalog, why is the 4 to 20 mADC input signal current type not available for the 2-wire type?

ITV series regulators require a power supply (24 VDC or 12 V) for driving the solenoid valve.
Therefore, pressure control is not possible with only a 4 to 20 mA input signal. Note) Old IT1000/2000/4000 series regulators of the 4 to 20 mA input signal current type were a 2-wire type, but they were designed to not require a power supply voltage.
