3.2.2 Supply via two MINI MCR-SL-PTB… power terminals
If you are using two MINI MCR-SL-PTB... for supplying the connected
MINI Analog modules, you are only allowed to connect one power supply per power
terminal. Likewise, you should position the two modules at either end of the DIN rail in
order to limit the maximum short-circuit current in the event of an error, see
Figure 3-6 on page 18. Please also observe the maximum permissible total current here
of 2 A if redundant power supply is desired. To increase the total number of signal condi-
tioners, a maximum current of 4 A can be supplied via both power terminals (NOTE, no
redundancy). The maximum number of MINI Analog devices is therefore equivalent to
the calculation in Section 3.2 on page 14.

Example for the supply via two MINI MCR-SL-PTB… power terminals
As in the previous example, the goal is to provide a redundant supply to
32 MINI MCR-RTD-UI-NC temperature measuring transducers (item no. 2902849),
ten configurable MINI MCR-SL-UI-UI-NC signal conditioners (item no. 2864150), with
4 mA ... 20 mA current output and 40 MINI MCR-SL-UI-F frequency converters
(item no. 2864082) at an operating voltage of 24 V DC.
First determine the current consumption of the modules from the packing slips again. For
the temperature measuring transducers it is 27 mA per module and for the configurable
transducers it is 21 mA at the desired current output. The frequency converters require
10 mA each.
Then determine the maximum total current consumption of all 82 modules.
