3.5 Auxiliary analogue output( Optional )
The auxiliary analogue output may be 0..20 mA, 4..20 mA, 0..5 V
or 0..10 V and the option must be configured both in the module
provided and in the indicator. Once installed, this interface is activated
on assigning the value 2( 0..20 mA ), 3( 4..20 mA ), 4( 0..5 V ) or 5( 0..10 V )
to the
Opt
parameter.
Once activated, the analogue output may be set up as direct
or inverse and the variation margin of the signal may also be set up by
the user.
Direct Output (
AOut.S
= 1
)
means that the value of the output signal
increases along with the process variable.
Inverse Output (
AOut.S
= 0
)
means that the value of the output signal
falls as the process variable increases.
Likewise, it is possible to set up the minimum (
AOut.L
) and
maximum (
AOut.H
) value of the process variable between which the
analogue output will vary between its minimum and maximum.
For example, an instrument with a type J thermocouple input
has a scale of 0..600°C. If this instrument has an analogue output of 4..20
mA, it is possible to set up
AOut.L
= 100°C and
AOut.H
= 500°C with which
the analogue output will take the following values:
Process (°C)
