Function Description
Input/analogue output scaling capability
Working of the analogue output (Y) versus the input variable (X) - (input/output scaling capability)
Figure A
The sign of measured quantity
and output quantity remains
the same. The output quantity
is proportional to the mea-
sured quantity.
Figure D
The sign of measured quantity
and output quantity remains
the same. With the measured
quantity being zero, the output
quantity has the value
Y1 = 0.2 (live zero output).
