Description
Description
The DRSL-DC1 isolated repeaterprovides a competitive choice interms of both price and technologyfor galvanic isolation of currentsignals to SCADA systems or PLCequipment. The unit provides isolationand 1:1 conversion of standardcurrent signals.
The unit offers isolation betweeninput, output and supply. Providessurge suppression and protectscontrol systems from transients andnoise. The DRSL-DC1 also eliminatesground loops and can be used formeasuring floating signals. Lowpower consumption facilitates DIN railmounting without the need for any airgap. Measurement ranges are factorycalibrated. The unit operates over awide temperature range from-25 to 70°C (-13 to 158°F).
