Notes: When connecting an inductive load (such as a solenoid valve) to the output DO signal, do not
connect the DO signal directly to the inductive load. It is best to connect through a relay to protect
the DO output contact so that power surges generated when the inductive load switches between
ON and OFF do not damage the DO output contact. If you must connect the inductive load directly,
connect a flywheel diode to the inductive load using a parallel connection to protect the DO
contact.
Figure 5.37 shows the PNP wiring method.
