Description
Description
The DRSL-SP3 bipolar isolatedsignal conditioner/splitter provides acompetitive choice in terms of bothprice and technology for galvanicisolation of process voltage orcurrent signals to SCADA systemsor PLC equipment. Two processoutputs are provided which mirrorthe single process input.
The DRSL-SP3 can be used forsignal conversion of standardbipolar analog process signalsinto two individual unipolar orbipolar analog signals. The unitoffers 4-port isolation, providessurge suppression and protectscontrol systems from transientsand noise. The DRSL-SP3 alsoeliminates ground loops and canbe used for measuring floatingsignals. Low power consumptionfacilitates DIN rail mounting withoutthe need for any air gap. Factorycalibrated measurement ranges areeasily configured via DIP switches.The unit operates over a widetemperature range from -25 to 70°C(-13 to 158°F).
