2.4 Connecting the power supply
The system bus communication channel on the XN300 slice modules is pow-
ered with the 5 V on the system bus.
In addition, the system bus provides a 24 VDC supply voltage used to inter-
nally power the XN300 slice modules. Modules with high power consump-
tion levels, however, will also need an additional power supply.
The XN-312-GW-CAN gateway powers the system bus with 5 VDC/1.6 A and
24 VDC/1.6 A.
The following XN300 slice modules require an external 24 VDC power supply
as well:
•
XN-322-8DO-P05
•
XN-322-12DO-P17
•
XN-322-16DO-P05
•
XN-322-8DIO-PD05
•
XN-322-16DIO-PD05
•
XN-322-16DIO-PC05
•
XN-322-8AO-U2
•
XN-322-4AIO-I
•
XN-322-8AIO-I
•
XN-322-1DCD-B35
•
XN-322-1CNT-8DIO
External 24 VDC voltages can be distributed using an XN-322-4PS-20 power
distribution module or XN322-18PD-P and XN-322-18PD-M field potential dis-
tributor modules:
Chapter 4 “Power supply XN-322-4PS-20”, page 29,
Chapter 6 “Power distri24 V XN-322-18PD-P”, page 37,
Chapter 5 “Power distribution 0 V XN-322-18PD-M”, page 33.
You can use the XN300-Assist software program for assistance with engi-
neering and commissioning.
DANGER
In safety-relevant applications, the power supply used to power
the XN300 system must be a PELV power supply unit.
