The layout of the printed circuit board for the input/output board B–I/O-1 is illustrated
in the following figure.
Figure 3-14 Input/output board B–I/O-1 with representation of the jumper settings required
for the board configuration
The set nominal currents of the current input transformers and the selected operating
voltage of binary inputs BI21 to BI24 according to Table 3-14 are checked. All jumpers
must be set for one nominal current, i.e. one jumper (X61 to X64) for each input trans-
former and additionally the common jumper X60. The jumper X64 determines the
rated current for the input I
phase currents. In models with sensitive ground fault current input there is no jumper
X64.
