DNC-T2020-R20产品概述
The DNC-T2003 through DNC-T2032 controls are output sequencers with an ad justable ON TIME, OFF TIME, and LAST OUTPUT. Upon application of power to the L1 and L2 terminals with the high pressure switch co ntacts c losed, the OFF TIME is initiated. At the end o f the preset OFF TIME, output 1will turn on for the preset ON 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.
