2.5.4 Signal contact
Only device variants featuring supply voltage with characteristic value C
(24 V DC ... 48 V DC), K (60 V DC ... 250 V DC / 110 V AC ... 230 V AC,
50 Hz ... 60 Hz) or W (24 V DC) have a signal contact.
For the signal contacts to be connected, make sure that the following
requirements are met:
The electrical wires are voltage-free.
The connected voltage is limited by a current limitation device or a fuse.
Observe the electrical threshold values for the signal contact.
See “General technical data” on page 63.
Connect the signal contact lines according to the pin assignment with a
suitable socket.
Plug the socket into the M12 plug on the device.
The tightening torque of the locking screw is 5.3 lb-in (0.6 Nm).
2.6 Operating the device
By connecting the supply voltage via a 7/8" plug or a twisted pair cable
(Power over Ethernet), you start the operation of the device.
