A quad-output 4-20 mA current loop splitter/retransmitter from Laurel Electronics, with isolation and adjustable outputs for industrial signal distribution.
The QLS device splits a single 4-20 mA, 1-5V, 0-5V or 0-10V input signal into four independent 4-20 mA outputs. Each output can be adjusted for zero and span, and features ±10V common mode isolation. It supports both AC and DC power options and includes diagnostic LEDs and loop current test points. The device solves problems with traditional series current loops by allowing independent operation of each output loop.
The unit is designed for DIN rail mounting and is compact, weighing only 159 g. It can power 2- or 3-wire transmitters and includes specifications for voltage compliance, load regulation, and environmental conditions.
