Register wiring
External DC+:
Yellow
External ground: Brown
Pulse output:
White
Analog output: Green
DC input:
8 to 24 VDC; 20 to 40mA
Outputs:
•
Analog 4 to 20mA output; external load of 0 ohms to 250 ohms; flow rate is linear scaled between 4mA minimum and
20mA maximum set points.
•
Pulse output with internal pull-up resistor (1 KΩ); optional open collector output when the jumper is removed. Please
open the battery compartment. The jumper may only be removed if no external voltage is present. The output is scalable
in pulses per liter or pulses per gallon.
