The DRSL-DC1 isolated repeater
provides a competitive choice in
terms of both price and technology
for galvanic isolation of current
signals to SCADA systems or PLC
equipment. The unit provides isolation
and 1:1 conversion of standard
current signals.
The unit offers isolation between
input, output and supply. Provides
surge suppression and protects
control systems from transients and
noise. The DRSL-DC1 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. Measurement ranges are factory
calibrated. The unit operates over a
wide temperature range from
-25 to 70°C (-13 to 158°F).
