The Model QLS from Laurel Electronics Inc., Costa Mesa, CA, is a quad output 4–20 mA loop splitter and retransmitter with ±10 V common-mode isolation between inputs and outputs. The device sources up to 4 independently adjustable 4–20 mA outputs from a single input. Input to the quad loop splitter can be 4–20 mA, 1–5 V, 0–5 V, or 0–10 V; an excitation output is provided on the signal input side to drive a 2- or 3-wire transmitter at 24 VDC and up to 30 mA. Outputs can share a common ground. Inputs and outputs are mutually isolated to ±10 V. If any device in an output loop is removed from a loop or fails, or if a wiring fault occurs, the other loops continue to operate properly.
