Input/Output Board A–I/O-2 for 7SJ62.../FF
The layout of the printed circuit board for the input/output board A–I/O-2 is illustrated in the following figure.
The set nominal currents of the current input transformers and the selected operating voltage of binary inputs
BI4 to BI11 are checked.

Figure 3-14
The jumpers X60 to X63 must all be set to the same rated current, i.e. one jumper (X61 to X63) for each input
transformer and in addition the common jumper X60. The jumper X64 determines the rated current for the
input Ι and may thus have a setting that deviates from that of the phase currents.
N
In models with sensitive ground fault current input there is no jumper X64.
The measuring range of the voltage inputs is defined via jumpers X80 to X85. For 7SJ62, the range 170 V
must be set, as shown in
