ANALOG OUTPUT
The analog output of the NEO-7 is a loop powered 4-20 mA control circuit. The typical way to use this feature
is to connect a positive supply to the Power (+) input terminal and to sense the current flow out of the Power (-)
output terminal with a sampling resistor as shown in the following diagram.
The cabling should be a shielded twisted pair to minimize EMI interference. Typically 20 to 24 gauge wire is
used in this application. To access the terminals, gently remove the display from the housing.
When wiring is completed, restore the display to the housing and replace the cover.
The NEO-7 series can operate without the display. When wired and powered correctly, the sensor will
continue to provide a proportional 4-20 mA signal.
