Analog I/O Units
Analog Outputs
CPU Unit
Note Word (n + 1) can be used for either the range code or the analog output set value.

Where "n" is the last output word allocated to
the CPU Unit, or previous Expansion Unit or
Expansion I/O Unit.
The I/O signal range is set by wiring the I/O terminal and by writing the range
code to the Analog I/O Unit's output word.
I/O Terminal Arrangement
Note When using current inputs, short terminal V IN1 with I IN1
and terminal V IN2 with I IN2.

Range Code
The range code must be set for the Analog I/O Unit to convert data.
The 8 range code settings provide 8 combinations of signal ranges for the ana-
log inputs and analog output, as shown in the following table.
