Digital Outputs
The three digital outputs are Dispenser Ready, Fault
Present and In Cycle. These outputs perform high-side
switching of 24 VDC and require a 24 VDC current sink-
ing input at the automation controller. See F
IG. 41. If the
automation controller uses 24 VDC relay coils to receive
I/O signals, the signals should be connected as shown
in F
IG. 41.
If the automation controller inputs are current sourcing
or use a voltage other than 24 VDC, relays with 24 VDC
coils must be used as shown in F
IG. 41.
