(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
