Digital Input Assignment
Click on the radio button that best describes the devices that you have connected to the digital inputs for
each input labeled 1 through 6. Make sure that you select the type of device that is actually wired to that
terminal of the card!
Not Used should be selected if nothing is attached to that input.
Paddlewheel Flow meter
should be selected if a high frequency (greater than 10 Hz) Hall Effect
paddlewheel flow meter is connected to that input. This option will give you the ability to specify a K
Factor to convert contact closures into a flow rate.
Contact Flow meter should be selected if a low frequency (less than 10 Hz) Hall Effect or reed switch
style water meter contactor is connected to that input. This option will give you the ability to specify the
volume of water that will give a contact (generally in multiple gallons or liters per contact).
Generic Input should be selected if the digital input state (open or closed) will indicate an alarm
condition or if the input state needs to be logged. The WebAlert allows you to specify a custom
message to be delivered if the contact is open or closed.
Generic Counter should be selected if you need to keep track of the rate of contact closures, or the
total number of contact closures.
