Example for supply via a MINI MCR-2-PTB… power terminal

The goal is to supply 32 MINI MCR-2-RTD-UI temperature measuring transducers

(item no. 2902049), ten configurable MINI MCR-2-UI-UI signal conditioners

(item no. 2902037), with 4 mA ... 20 mA current output and 40 universal

MINI MCR-2-UNI-UI-UIRO signal conditioners with switching output (item no. 2902026)

at an operating voltage of 24 V DC.

First determine the current consumption of the modules from the packing slips. For the

temperature measuring transducers it is 31.5 mA per module and for the configurable

transducers it is 25 mA at the desired current output. The universal signal conditioners

with switching output require 31.5 mA each.

Then determine the maximum total current consumption of all 82 modules.

The total current consumption of 2518 mA is less than the maximum permissible current

for supply via the MINI MCR-2-PTB…. The fuses connected upstream of both power

modules should each have a nominal current of 4000 mA. To ensure that the fuses

definitely trip in the event of a short circuit, the 24 V DC supply in this example is provided

by a QUINT4-PS/1AC/24DC/3.8/SC (item no. 2904599). The structure is shown in

Figure 4-5 on page 31. The wiring is as shown in Figure 4-4 on page 29.
