The DRSL-LPO Series DIN rail
2-wire transmitter 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 host
(output) current signal loop. Input
transmitter (Tx) power supply of
3.5 to 32.5V is provided.
The DRSL-LPO 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).
