10 SCT-1100 Weight Transmitter
2.6 Wiring Schematic
Figure 2-4. SCT-1100 Wiring Schematic
The
CELL1
terminal board of the indicator can be connected to a six-wire load receiver;
CELL2
,
CELL3
and
CELL4
are only for four-wire connection. See Figure 2-4 .
The
I/O Boot
is the connector for the connection of the alibi memory board or for the clock board.
The maximum resistance applicable on the output current is 350
Ω
and the minimum resistance applicable on
the output voltage is 10 k
Ω
.
