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 3-12 Input/output module A–I/O-2 for devices (releases .../FF and higher) with representation of the
jumper settings required for the board configuration
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
I
N
and may thus have a setting that deviates from that of the phase currents. 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 3-12. The range may not
be changed to 200 V.
