3.3 Supply via a system power supply
If there is no 24 V DC supply in the control cabinet or in the terminal box for supplying the
MINI Analog signal conditioners, you can use a QUINT4-SYS-PS/1AC/24DC/2.5/SC
(item no. 2904614). These power supplies, which have been developed specifically for
measurement and control technology, enable the signal conditioners to be supplied
directly from a 230 V AC supply via the TBUS DIN rail connector. These power supplies
are simply snapped onto the TBUS and deliver a maximum current of 2.5 A. To increase
performance, up to two QUINT4-SYS-PS/1AC/24DC/2.5/SC can also be snapped on.
This means that a total current of 5 A can be supplied. Please note, however, that
redundant supply is not possible for currents greater than 2.5 A. A 6 A, 10 A or 16 A
characteristic B miniature circuit breaker should be used to protect the primary side.
Calculate the maximum number of modules with the aid of the relevant packing slips
using the formula below.
Example for supply via a system power supply
The goal is to supply 65 MINI MCR-SL-PT100-UI-200-NC temperature measuring
transducers (item no. 2864370).
First determine the current consumption of the modules from the packing slips. For this
temperature measuring transducer it is 21 mA per module.
Then determine the maximum total current consumption of all 65 modules.
The total current consumption of 1365 mA is less than the maximum permissible current
for supply via the QUINT4-SYS-PS/1AC/24DC/2.5/SC (item no. 2904614). The structure
is shown in Figure 3-8 on page 21.
