Note: Outlet OUTA(OUT9) and OUTB(OUT10) of 1:OC gate are multiplex ports, which
can be connected with large screen and stepping motor.
Note: Mainboard input port INA corresponds to IN5,INB corresponds to IN6, and
high-speed pulse port is common input port corresponding to IN7.

This instrument has 10 common switch inputs (IN1-IN10), and the
common terminal COM is not connected to any electrical node inside
the instrument. At the same time, the positive power supply (+V)
and the negative power supply (-V) are led out inside, so the
common terminal can be connected to +V or -V or not according to
different needs. Each input port can be connected with a button,
a trigger switch, a relay contact point, a proximity switch,
etc.You can also input a DC voltage signal (6-24V). See the
following figure for specific common connections.
Figure 4.1 Schematic diagram of switch input connection
Note: The common point COM in the figure can also be connected with+V. At this
time, one end of the button should be connected with-V. You can choose different
connection methods according to your needs.
