Quick Disc. Assy. Black TSD1121-22 Knob, Small TSD1121-23 Knob, Large I/O Configuration and End of Cycle Switch Upon completion of a dispense cycle, an open collector circuit closes and remains closed until the next dispense cycle. This circuit can be used to signal back to a host computer, start another device in sequence, or drive any other operations that need to be tied to the completion of the dispense cycle. Upon closure, (end of dispense cycle), 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: At the end of each 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 DX-250/255 controller.
