RSC -AAM60/RSO22..., RSO4...., RSO60...
In order to achieve a 4 to 20
mA signal from a 12 or 24
VDC source, a resistor and a
potentiometer should be con-
nected in series with the volt-
age source and the RSC con-
troller.

We define the I
24 mA, which means that the
series resistors must be:
R
12 V/24 mA - 250

24 V/24 mA - 250

If the minimum current is
defined to be e.g. 2.4 mA
and the 250
resistance of the RSC is
also calculated in:
R
12/2.4 - 250 - 250 = 4500
R
24/2.4 - 750 - 250 = 9000
