The LRS is a fully floating 4-20mA signal isolator that provides up to 2500Vrms isolation between the input loop and the output loop. The LRS can be used as a noise filter or reducer of common mode noise in some 4-20mA current loops. The LRS is manually adjustable to suit the individual loop loading, the adjustments being done from the top of the module via multi-turn potentiometers.

The LRS is factory calibrated for a 250 ohm output load unless otherwise specified.
