Function Description

Input and output scaling capability.
Working of the analogue outputs (y) versus input variables (x)
Figure A
The sign of measured quant-
ity and output quantity re-
mains the same. The output
quantity is proportional to the
measured quantity.
Figure B
The sign of measured quant-
ity and output quantity
changes simultaneously. The
output quantity is proportion-
al to the measured quantity.
Figure C
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.

NOTE: In case of fault of first insulation the current from the measuring inputs to the ground is lower than 2 mA.
(*) The given insulation is granted among outputs plugged in different slots. The modules equipped with two or four outputs have
therefore non insulation among the outputs. (**) Insulation between the 2 outputs of the same module is 200V for 1 min.

Figure D
The sign of measured quant-

measured quantity being
zero, the output quantity
already has the value
Y1 = 0.2 Y2.

Figure E
The sign of the measured
quantity changes but the one
of the output quantity
remains the same. The out-

es from value X1 to value X2
of the measured quantity.

Figure F
The sign of the measured
