Basic Unit
The DRA-ACT-2I AND
DRA-ACT-2V Series are isolated
2-wire loop-powered ac current and
ac voltage input DIN rail mount
signal conditioners that convert the
measured input into a proportional,
linear and highly accurate 4-20 mA
output current. The DRA-ACT-2I
Series of ac current input models
includes models for 0 to1 Aac and
0 to5 Aac inputs with 4 to20 mA
output. The DRA-ACT-2V Series of
ac voltage input models includes
models for 0 to150 Vac, 0 to250 Vac
and 0 to400 Vac inputs again with
4 to 20 mA output.
For complete safety, an internal
transformer isolates the signal
conditioner input from the output
thus enabling these units to
withstand large momentary inputs.
Complete input to output isolation,
high surge current capacity and high
output signal-to-noise ratio make
these signal conditioners highly
immune to ground loop signals and
RFI. These transmitters are also
equipped with a “test” terminal
which facilitates monitoring of the
output current by measuring the
voltage drop across an internal
10 Ohm resistor without disturbing
the 4 to 20 mA process loop.
