(NPN Linear 2-wire Output)
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.
Note:
When the contact is short-
circuited, a current of approxi-
mately 13 mA will flow at a volt-
age of approximately 12 V.
Input resistance: 10 k
