Note 1. Connect the A9/B9 terminal and the terminal for
NPN.
Connect the A9/B9 terminal and the terminal for
PNP.
(Use the enclosed short bar.)
2. The COM terminals are wired inside the Connec-
tor-Terminal Block Conversion Unit.
Note 1. The polarity for input power supply connections
indicated with dotted lines (
