11. I/O CONFIGURATION AND END OF CYCLE FEEDBACK
During a dispense cycle, an open collector circuit closes and remains closed while
the valve is dispensing. Pin 3 and 4 can be as feedback signal to synchronize with
other devices. Power from an external source is allowed to pass through the circuit
to operate a 5 to 24 VDC load. Power consumption must not exceed 250 mA. The
load could be a relay, solenoid, counter, LED, or any device that will operate within
a 5 to 24 VDC range and a maximum of 250 mA.
Note: During the dispense cycle, pin 3 will be grounded. Please make sure the
external device (your machine that controls the dispenser/controller) has the same
ground as the controller.
Pin 7, 8, and 9 = Available
