QLS Quad Output 4-20 mA Current Loop Splitter / Retransmitter With ±10V common mode isolation between input & outputs
The QLS is a quad-output 4-20 mA current loop splitter/retransmitter that generates four independently adjustable 4-20 mA outputs from a single input source (4-20 mA, 1-5V, 0-5V, or 0-10V). It features ±10V common-mode isolation between input and outputs, allowing operation in different grounding environments. The device supports two power options: QLS-1 (85-264 Vac) and QLS-2 (10-48 Vdc or 12-32 Vac). Each output includes potentiometers for zero and span adjustment, a yellow LED for loop continuity, and a current test point for measurement without breaking the loop. The unit is designed for industrial applications and includes safety and environmental specifications for proper operation.
