the output quantity remains
the same. The output quant-
ity steadily increases fr om
value X1 to value X2 of the
measured quantity.

Outputs
Open collector outputs: The
load resistance (Rc) must be
calculated so that the closed
contact current is lower than
100mA; the VDC voltage must
be lower than or equal to 30V.
VDC: power supply voltage
(external). Vo+: positive output
contact (open collector transis-
tor). GND: ground output con-
tact (open collector transistor).
