Output Ranges of the Analog Output Module SM 332;

AO 4 16 bits

Connecting the analog outputs

You can connect the outputs as voltage or current outputs, or disable them. You

perform connection of the outputs with the "output type" parameter in STEP 7.

Unused channels

So that unused output channels of the SM 332; AO 4

de-energized, you must set the "output type" parameter to "disabled" and leave the

terminal open.

Output ranges

You program the output ranges for voltage and current outputs in STEP 7.

Table 11

Selected Type of Output

Voltage

Current

Default settings

The default settings of the module are "Voltage" for the output type and "" 10 V"

for the output range. You can use this combination of output type and output range

without parameterizing the SM 332; AO 4

Substitute values

You can configure the SM 332; AO 4

as follows: Outputs De-energized, Hold Last Value or Inject Substitute Values. If

you inject substitute values, they must be within the output range.
