Connection cable shield
The shield of the connection cable is on the thread of
the M12 connector plug.
The thread of the M12 connector plug is part of the
metallic housing. The housing is at the potential of
the functional earth via pin 8.
NOTICE
Maximum loading of the switching outputs
Do not load the switching outputs with more than 60 mA at +18 … +30 VDC.
The switching outputs are protected against short-circuit, overcurrent, overvoltage, excess tempera
-
ture and transients.
NOTICE
Maximum cable length 10 m
Operation of the RS 232 interface is only permissible with shielded cables with maximum cable length
of 10 m.
