DRSL LPO 1 DIN Rail Output Loop Powered Isolators w 1 or 2 Channel Models 13011

 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).
