Product Overview

The QLS-1 is a Quadruple Output Loop Splitter/Retransmitter with common mode isolation between input and outputs. It overcomes problems of simply placing loads in series in a single 4 to 20mA loop. In such a configuration, the devices in the loop cannot share a common ground, but must be electrically floating, which is often not possible. The transmitter voltage compliance limit may be exceeded, since the voltage drops across loads in series are additive. Each output loop provides two potentiometers for ±10% fine adjustment of zero and span. This allows a multimeter to be used to measure the loop current without breaking the loop.
  • 95 to 264VAC voltage range
  • Green LED lamp power on indication
  • 3.5W maximum, all loops delivering 20mA power consumption
