The DRSL-U isolated universal
input DIN rail signal conditioner
provides a competitive choice in
terms of both price and technology
for galvanic isolation of process
signals to SCADA systems or
PLC equipment.
The DRSL-U
accepts thermocouple, RTD, linear
resistance, potentiometer, voltage
or current input and converts these
signals to linear voltage or current
output. The unit offers isolation
between input, output and supply,
provides surge suppression and
protects control systems from
transients and noise.
The DRSL-U
also eliminates ground loops and
can be used for measuring floating
signals. Low power consumption
facilitates DIN rail mounting without
the need for any air gap. The
DRSL-U is easily configured by using
the DRSL-DISPLAY programming
interface in conjunction with the
DRSL-ADAPTOR configuration
adaptor.
The DRSL-DISPLAY has
a 4 line LCD display with scrolling
help text in 7 languages (English,
French, German, Italian, Spanish,
Danish and Swedish) which guides
the user through all the configuration
steps. The DRSL-U is designed
with electronic hardware switches,
consequently it is not necessary to
open the device to set any internal
DIP-switches.
