Analog output configuration

6.15.1

Analog output

The two output signals (current and voltage) are available simultaneously. Adjust

ConF / Out.3 / O.tYP to

select the output type which should be calibrated.

ConF / Out.3:

O.tYP

=

1

Out.3 0...20mA continuous

=

2

Out.3 4...20mA continuous

=

3

Out.3 0...10V continuous

=

4

Out.3 2...10V continuous

Parameter

O.Src defines the signal source of the output value.

Example:

O.Src =

3

signal source for

Out.3 is

the process value

Scaling of the output range is done via parameters

Out.0 and Out.1. The values are specified in units of the

physical quantity.

Out.0

=

-1999...9999

scaling

Out.3

for 0/4mA or 0/2V

Out.1

=

-1999...9999

scaling

Out.3

for 20mA or 10V

Example: output of the full input range of thermocouple type J (-100 … 1200 °C)

Out.0 = -100
Out.1 = 1200

Example: output of a limited input range, e.g. 60.5 … 63.7 °C)

Out.0 = 60.5
Out.1 = 63.7

+

Please, note: the smaller the span, the higher the effect of input variations and resolution.

g

Using current and voltage output in parallel is possible only in galvanically isolated circuits.

g

Configuration O.tYP = 2 (4 … 20mA) or 4 (2...10V) means only allocation of the reference value (4 mA or 2V)
for scaling of output configuration Out.0. Therefore, output of smaller values is also possible rather than
output limiting by reference value 4mA / 2V.

g

Configuration O.tYP = 0/1 (0/4...20mA) or 2/3 (0/2...10V) determines, which output should be used as a
calibrated reference output.
