CPT-DIN
Function Description
Figure A
The sign of measured quant-
ity and output quantity re-
mains the same. The output
quantity is proportional to the
measured quantity.
Input and output scaling capability. Working of the analogue outputs (y) versus input variables (x)
Figure B
The sign of measured quant-
ity and output quantity re-
mains the same. On the
range X0...X1, the output
quantity is zero. The range
X1...X2 is delineated on the
entire output range Y0 =
Y1...Y2 and thus presented in
strongly expanded form.
Figure D
The sign of the measured
quantity changes but that of
the output quantity remains
the same. The output quant-
ity steadily increases from
value X1 to value X2 of the
measured quantity.
Figure C
The sign of measured quant-
ity and output quantity re-
mains the same. With the
measured quantity being
zero, the output quantity
already has the value
Y1 = 0.2 Y2.
Live zero output.
