(1) When using an inductive load (such as a solenoid valve), either use a
built-in diode for absorbing the counterelectromotive force or install an ex-
ternal diode.
(2) Two V terminals and two G terminals are provided for use as I/O power
supply terminals. One set of terminals is used for the power supply for the
Unit, and the other set is used for the supply power to the next Unit. Use
a maximum current of 4 A per terminal.
(3) Wire colors have been changed according to revisions in the JIS stan-
dards for photoelectric and proximity sensors. The colors in parentheses
are the wire colors prior to the revisions.
