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.
