①
24 VDC Sensor Power Out. For
additional noise immunity, connect "M"
to chassis ground even if not using
sensor supply.
②
For sinking inputs, connect "-" to "M"
(shown). For sourcing inputs, connect
"+" to "M".
Note 1: X11 connectors must be gold. See
the S7-1200 System Manual, Appendix C,
Spare Parts for order number.
