Basic Unit
The DRA-ACT-4I AND
DRA-ACT-4V Series are isolated
4-wire 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-4I
Series of ac current input models
includes models for 0-1 Aac and
0-5 Aac inputs with a 4-20 mA
output. The DRA-ACT-4V Series of
ac voltage input models includes
models for 0-150 Vac, 0-250 Vac
and 0-400 Vac inputs again with a
4-20 mA output. Standard
instrument power is 115 Vac, 50/60
Hz. Units can also be configured for
optional 230 Vac, 50/60 Hz power.
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. Zero and span trimmers
accessible from the front panel of
these units facilitate fine tuning.
