Figure 2-Wire Power Supply Type
This method supplies power to the transmitter, and receives the transmitter output signals as the
current pulse signals. By using the input load resistance (select from None,200 ohm, 510 ohm, 1
k ohm), the current signal is converted to the voltage level pulse and receives it.
