Input terminals
• All COM terminals are at the same potential.
• When connecting a power supply between 1-9, A, B and COM, switch SW5 to the external power
supply (EX).
• You can switch between the sink/source logic of input terminals by using SW6.
(Wiring example)
• Indicates the factory default setting.

terminal
You can select terminal functions
using the parameter settings corre-
sponding to each terminal. You can
switch between the sink logic and
source logic by switching SINK/SRC
of SW6.
Voltage between each input/COM
• ON voltage Min. DC18V
• OFF voltage Max. DC3V
• Maximum allowable voltage
DC27V
• Load current 5.6mA (at DC27V)

Pulse
input-A
This is a terminal for pulse input. A
and B terminals can be used also as
an input terminal.
Terminal functions are selectable
according to the parameter settings
for each terminal.
The maximum input pulse rate is
32kpps.
