Details
A system resp. the 216MB6. equipment rack can be equipped with one or two redundant auxiliary d.c. supply units (DC/DCconverters).
Fig. 2.1 shows the auxiliary d.c. supply system witheither two 216NG61, 216NG62 or 216NG63 units.
All electronic units and I/O modules have been designed to operate with redundant auxiliary d.c. supplies.
As long as one of the two 24 V supplies is available, the correct operation of all the equipment's functions is assured.
The B448C parallel bus has two redundant auxiliary d.c. supply lines designated USA and USB and the redundant supplies for the electronic units are achieved by connecting them to both.
The 216NG6 units also provide the auxiliary d.c. supply for the I/O modules. The corresponding auxiliary voltage UP (24 V)/ZP (0 V) is distributed to the individual I/O modules via a terminal block.
