Description
Description
The DRSL-LPO Series DIN rail2-wire transmitter isolators provide acompetitive choice in terms of bothprice and technology for galvanicisolation of current signals toSCADA systems or PLC equipment.These units provide isolation and1:1 conversion of standard currentsignals and are powered by the host(output) current signal loop. Inputtransmitter (Tx) power supply of3.5 to 32.5V is provided.
The DRSL-LPO series offers isolationbetween input and output, providessurge suppression and protectscontrol systems from transients andnoise. These units also eliminateground loops and can be used formeasuring floating signals. Lowpower consumption facilitates DIN railmounting without the need for any airgap. Measurement ranges are factorycalibrated. These isolators operatesover a wide temperature range from-25 to 70°C (-13 to 158°F).
