Description
Description
The DRSL-DC2 isolated DINrail signal conditioner provides acompetitive choice in terms of bothprice and technology for galvanicisolation of process voltage orcurrent signals to SCADA systemsor PLC equipment. The DRSL-DC2can be used for signal conversionof standard process voltage orcurrent signals. The unit offersisolation between input, output andsupply, provides surge suppressionand protects control systems fromtransients and noise.
The DRSL-DC2 also eliminatesground loops and can be used formeasuring floating signals. Lowpower consumption facilitates DINrail mounting without the needfor any air gap. Factory calibratedmeasurement ranges are easilyconfigured via DIP switches. Whenthe input is configured for 2-wiretransmitter mode, the DRSL-DC2provides the current loop supplyvoltage. The unit operates over awide temperature range from -25 to70°C (-13 to 158°F).
