Pin 5
The 7/8" plug is laid out for a maximum current value of 9 A per pin. This must be taken into consideration when
looping supply power through.
The Connection Box must be connected to supply voltage within a range of 18 to 32 V DC.
U
System/Sensor
supplies the Connection Box and all connected sensors with voltage, and U
Digital I/O
is used to
supply voltage to the digital I/O ports.
Voltage from U
System/Sensor
must not be switched off during operation, and thus may not be connected via the
emergency off circuit, because the Connection Box would otherwise no longer be able to participate in com-
munication.
In any event, it must be assured that supply voltage – measured at the most distant user – is no less than
18 V DC from a system power supply standpoint.
To be observed in the feedback mode:
If digital I/O power supply is combined with power supply for the Connection Box, there’s a risk that
communication could be interrupted in the event of a short-circuit at the I/O devices.
