Supply options for MACX Analog (Ex)/MACX PL
105810_en_01 PHOENIX CONTACT 57
supply in this example is provided by QUINT-PS/ 1AC/24DC/ 3.5 power supplies (Order No.
2866747), which provide a short-circuit current of 15 A. The structure is shown in Figure 5-9
on page 57. The wiring is as shown in Figure 5-8 on page 56.
Figure 5-9 Example for supply via a TC-MACX-MCR-PTB power terminal block
The disadvantage here is that in the event that the power terminal block fails, the supply of
all signal conditioners is interrupted.
