introduction：（one）、Circuit specification： The circuit is made of3Individual relay composition，itsJ0Is the basic circuit component，It suffersplcOutput control of，Its normally open contact controls the on-off of the solenoid valve。Consider that the relay contact is easy to stick and the coil short circuit will cause loss of control and cause accidents，Increase byJ1、J2Two relays and resistors capacitance and other components，The contact is composed of the local relay、A protective circuit that breaks off immediately when the coil shorts，The circuit in the dotted green box in the figure is the main circuit，The remaining part is the relay contact adhesion or the solenoid valve coil short-circuit protection circuit。 circuitalJ0、J1The working voltage of the relay is12V，Its coil resistance value=Ro。J2Operating voltage=24V。J0spliceR1（Resistance value=Ro），reconcatenationR3（Resistance value=Ro/2），Attach toQ1.0Output end，Therefore appropriateQ1.0=1（+24V）whenJ0voltage=12V。DW1Pressure regulator and6VPilot lampZ3After series，withR3In par
