Signal input terminal
100 to 240 VAC
or 12 to 24 VDC
Note: Terminals 7 to 13 are connected internally.
Terminals 7 and 11 are mutually isolated.
When inputting the external control signals and input signals
through the open collector:
Transistor Inputs:
ON: Residual voltage must be 3 V max.
OFF: Leakage current must be 1.5 mA max.
The switching capacity must be 20 mA or greater.
When the external signal input is short-circuited, a voltage of
approximately 5 V will be applied to between the terminals 5 to 7
and the COM terminal, and a current of approximately 18 mA
(nominal value) will flow.
Note: Check the power supply specifications of the mod-
el used before connecting the power supply.

NPN output sensor
Note: When the contact is short-
circuited, a current of approxi-
mately 13 mA will flow at a volt-
age of approximately 12 V.
Voltage pulse output sensor
Note: Connect the + side of the NPN
linear 2-wire input to terminal 1
and the − side to terminal 11.
Note: With voltage pulse input
not from a 3-wire sensor,
connect the + side to ter-
minal 3 and the − side to
terminal 11.
