LT Series (RS232/RS485 + analog)
LTE Series (Ethernet + analog)
LTS Serial-to-Analog Transmitter

Quad Current Loop Splitter (QLS)

A DIN-rail signal splitter/retransmitter that takes one process signal and drives four independent isolated 4-20 mA loops, so a single transmitter can feed meters, PLCs, recorders and loggers on different grounds.

Input 4-20 mA, 1-5 V, 0-5 V or 0-10 V; four independent 4-20 mA outputs
±0.02% max span error at 23°C; 2 ms rise, 7 ms settling to 0.1%
Per-loop ±10% zero/span trim, test point and LED; ±10 V common-mode between outputs

Laurel — common questions

How many Laurel instruments can be networked on one LTNET485?

The LTNET485 device server connects up to 31 Laurel meters or transmitters to Ethernet over an RS485 bus.

Are Laurel meters available for outdoor or wash-down areas?

Yes — the IPC cover and BOX2 enclosure provide NEMA 4X (IP67) protection for 1/8 DIN meters.
