Analog Outputs (
Options A1/2/3/4/6/8
)
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
NOTE
The common use of the analog outputs, the interfaces and the discrete inputs depends on their re-
spective combinations. Please pay attention to the combinations possible as described in the intro-
duction.
CAUTION
The function of the analog outputs is restricted during configuration via the side connector (ver-
sion 3.xxx). The parameter "Direct parametr." must be set to "NO" in order to make all analog outputs
available (refer to "Direct Configuration (from Version 3.0xx)" on page 34).
It is possible to configure a linear measuring range for each analog output and assign it to a specific measured
value (refer to Table 6-3). The -20/0/4 to 20 mA analog outputs may be configured as a -20 to 20 mA, 0 to
20 mA, or 4 to 20 mA output. The -10/0 to 10 V analog outputs may be configured as a -10 to +10 V or 0 to
+10 V output. The user may define the upper and lower limits of the analog input measuring range. Text may be
assigned to the input as well.
