The DRSL-LPI Series DIN rail input
loop powered isolators provide a
competitive choice in terms of both
price and technology for galvanic
isolation of current signals to
SCADA systems or PLC equipment.
These units provide isolation and
1:1 conversion of standard current
signals and are powered by the
analog input current signal loop.
The DRSL-LPI series offers isolation
between input and output, provides
surge suppression and protects
control systems from transients and
noise. These units also eliminate
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. These isolators
operates over a wide temperature
range from -25 to 70°C (-13 to 158°F).
