產(chǎn)品描述
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).
