The DC signal separators are used for galvanic separation of signal
circuits. The devices can transmit current signals of 0 to 20 mA, 4 to 20
mAand 0 to 50 mA
with a response ratio of 1:1.
The DC signal separators should be incorporated at the
design stage at all points where galvanic separation is necessary in the signal
circuit. DC signal separators can easily be added to a signal
circuit later on, since they do not
require power supply.
The DC signal separator provides
reliable separation:
-
for measurement signals in meshed control
loops
-
for devices with different signal potentials
-
to eliminate double earthing and related equalizing currents
-
for intrinsically safe and non-intrinsically safe circuits
-
for signals used to add currents
-
as process control interface module
