Product Description

Laurel QLS-1 Line Splitter

Not so good: A single 4-20 mA loop from a sensor is connector to a panel meter, a control valve, a recorder and a PLC in series. If the loop opens, all devices in the loop fail. When any device in a loop is removed, fails or if a wiring fault occurs, all other devices in the loop loose their 4-20 mA signal. The 4-20 mA signal to each load device cannot be individually
adjusted for calibration purposes.

With the Laurel QLS-1 you get fourour independent 4-20 mA loops with ±10V common mode isolation. If any of the output loops opens, only a single device is affected. The output loops can share a common ground. Diagnostics for each output loop are provided by a yellow LED
lamp to indicate loop continuity and by a test point across a 10: series resistor, where 200 mV corresponds to 20 mA. The test point allows a multimeter to measure the loop current without breaking the loop.

 

  • Accepts a 4-20 mA, 1-5V, 0-5V or 0-10V input signal
  • Drives four (4) independent 4-20 mA outputs proportional to input
  • Signal input and outputs can share a common ground
  • Remote grounds can differ by up to ±10V from local signal ground
  • Opening any output loop does not affect the other loops
  • ±10% zero and span fine adjustments for each output loop
  • Loop current test point for each output, where 200 mV = 20 mA
  • Indicator LED for each connected output
  • Powered by 85-264 Vac or 10-48 Vdc (optional)
  • Powers a 2- or 3-wire input transmitter at 24V with up to 30 mA
  • 22.5 mm (0.9″) wide case snaps to 35 mm DIN rail
  • Weighs only 159 g (5.6 oz)
