2, the choice of "timing program controller" to control the most appropriate, the controller has multiple inputs and outputs, the input can be connected to a number of switches and sensors, the output can be driven directly to the 24V solenoid valve, wiring is also very simple.
3, in particular, "Timing Program Controller" uses multiple optoelectronic isolation and electromagnetic isolation technology, anti-interference ability is very strong, very suitable for your application. You can go to the Beijing Multi-dimensional Precision Control website to learn more about the details, see the details and technical advice and other contact information.
