Current demand and power supply

The u-control controllers use three internal current paths:
The I system current path supplies the communication
SYS
part of the I/O modules; it is fed from the controller input
supply and cannot be interrupted by any module. The maxi-
mum current-carrying capacity of I
tion to be expanded with a maximum of 64 active modules
without having to refresh the power.
The I input current path supplies the input circuit of the
IN
input modules as well as the connected I
rent must be refreshed with UR20-PF-I (power feed in) mod-
ules as required. These UR20-PF-I modules isolate the input
current path towards the left (towards the controller), and as
a result start a new electricity segment towards the right.
The I output current path supplies the output circuit
OUT
of the output modules with power, as well as the connect-
ed I actuators. The current must be refreshed with the
L
UR20-PF-O (power feed-out), as required. These UR20-PF-O
modules isolate the output current path to the left (towards
the controller), and as a result start a new electricity seg-
ment to the right.
The design of the power supply being used must
take start-up peaks into account.
Power supply derating
The power supply is restricted according to the temperature.
The following values apply for the horizontal and vertical po-
sitioning of the u-remote station:

Equipment may become damaged if improperly rat-

▶ In order to achieve spezification according to UL 248-14
use a UL-approved Type-B automatic circuit breaker
(e. g. ABB Typ S201-B16) or use a fuse with a maxi-
mum of 10 A protection (e. g. ESKA Art. Nr. 522.227).
Equipment may become damaged by overcurrent!
▶ Auxiliary supplies as well as signal inputs and outputs
may not be used for supplying the station.

The current demand of the u-remote I/O-modules
can be found in the Remote-I/O-System
u-remote Manual.
All manuals are available to download from the
Weidmüller website.
Voltage interruption
The controllers meet severity level PS1 (maximum inter-
ruption time 1 ms) according to IEC 61131-2. If you want
to achieve severity level PS2 (maximum interruption time
10 ms), you must use a power supply that meets the require-
ments of severity level PS2.
