OF THE Series 16i/18i/21i
B–62443EN–2/03
102
Classification :24–V input, set to common 24 V or 0 V
Function :These eight input signals are provided as an interface
with a workpiece feeder. The signals can be used for
any purpose related to the mechanical unit. When the
skip function is used, however, FDI08 is used as a
skip signal. When the skip function is not used,
FDI08 can also be used for any purpose. The signals
are connected in parallel to another connector
CNWF.
Classification :Common selection
Function :When COMWF is connected to 0 V, FDI01 to FDI08
become common 24–V input signals. When
COMWF is connected to +24 V, FDI01 to FDI08
become common 0–V input signals. The signal
polarity changes accordingly. When FDI01 to FDI08
are used as common 24–V signals, a closed contact
makes the signals go to logical 1. When the signals
are used as common 0–V signals, a closed contact
makes the signals go to logical 0.
This signal is connected in parallel to another
connector CNWF.
Classification :24–V source output, 24–V/200–mA load
Function :These eight output signals are provided as an
interface with a workpiece feeder. The signals can be
used for any purpose related to the mechanical unit.
The signals are connected in parallel to another
connector CNWF.
Eight input signals and eight output signals can be used to control a
workpiece feeder.
DI = 8 points (general–purpose 24–V input)
DO = 8 points (general–purpose 24–V source output)
The signals are provided to make the workpiece feeder go forward or
backward.
