A touch switch an intermediate relay and two time relay control two solenoid valves, a solenoid valve instantly work another delay work, time to power off together, how to connect? Seeking map
? Your function with this control program is rich enough, this circuit can control the more complex action control.
Figure 4 is the control of the four solenoid valve circuit, you are to control the two solenoid valve, the direct two can, the input of the start switch, stop switch and proximity switches can be selected according to need, do not need no wiring, switch There is no limit to the location and order of the arrangement, according to the need to arrange.
You can use the watch control TPC4-4TD controller to achieve the use of DC 24V solenoid valve, the middle of the relay and two time relay can be saved without the table control with dozens of internal timer and program control functions, fully meet Your request. The realization of the function is also very easy, only need to set up a few lines of data on the function table can meet your control requirements.
