The DNC-T2010-BDC control is an output sequencer with an adjustable ON TIME, OFF TIME, and LAST OUTPUT. Upon application of power to the L1 and L2 terminals with the high pressure switch contacts closed, the ON TIME is initiated. At the end of the preset ON TIME, THE OUTPUT will turn OFF for the preset OFF TIME. The control will cycle through all selected outputs until the high and low pressure switch contacts are opened. If the pressure switch contacts open during the ON TIME, the output will complete the active ON cycle. The next time the high pressure switch is closed the next output in the sequence is fired. Pressure monitoring with no hysteresis is achieved by using only a high pressure switch. Placing a jumper across the high pressure input forces the control to run continuously. ?Universal voltage input: 12 to 24 VDC 50/60 Hz ?
