Basic Unit
The DRA-ACT-SI AND
DRA- ACT-SV Series are
self-powered ac current and ac
voltage input DIN rail mount signal
conditioners that use the measured
input to produce an accurate and
linear output current. These signal
conditioners have excellent
accuracy, linearity and stability
which make them unique.
The DRA-ACT-SI Series of ac
current input models includes
models for 0-1 Aac and 0-5 Aac
inputs with a choice of either 0-1 mA
or 0-20 mA output. The
DRA-ACT-SV Series of ac voltage
input models includes models for
0-150 Vac and 0-300 Vac inputs
again with a choice of either 0-1 mA
or 0-20 mA output. The output
current from all of these
self-powered models always starts
at 0 mA since these units are
powered from the measured signal.
Therefore, when the ac current or
voltage input is zero, the output
is zero.
For complete safety, an internal
transformer isolates the signal
conditioner input from the output
thus enabling these units to
withstand large momentary inputs.
The input to output isolation
provides high output signal-to-noise
ratio which makes these signal
conditioners highly immune to
ground loop signals and RFI.
