Laurel Electronics QLS-2 Quad Isolated Output Loop Splitter Retransmitter, 10-48 Vdc powered


Laurel Electronics QLS-2 Quad Isolated Output Loop Splitter Retransmitter, 10-48 Vdc powered by LAUREL ELECTRONICS at Band Electric. MPN: QLS-2. Hurry! Limited time offer. Offer valid only while supplies last. In many industrial applications, the same 4-20 mA signal from a transmitter needs to be sent to multiple devices. Simply connecting the loads in series would cause a number of problems. The devices in the loop then cannot share a common ground. When any device in a loop is removed, fails, or if a wiring fault occurs, all other devices in the loop also lose their signal. The transmitter (or signal conditioner) voltage compliance limit may be exceeded, since the voltage drops across loads in serie

Product Description & Reviews

In many industrial applications, the same 4-20 mA signal from a transmitter needs to be sent to multiple devices. Simply connecting the loads in series would cause a number of problems. The devices in the loop then cannot share a common ground. When any device in a loop is removed, fails, or if a wiring fault occurs, all other devices in the loop also lose their signal. The transmitter (or signal conditioner) voltage compliance limit may be exceeded, since the voltage drops across loads in series are additive. The Laurel QLS Quad Loop Splitter solves these problems by sourcing up to 4 independently adjustable 4-20 mA outputs from a single input. If any device in an output loop is removed from a loop or if a wiring fault occurs, the remaining loops continue to operate properly. Each loop only drives a single load, avoiding compliance problems. Features: 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. Outputs can share a common ground. Grounds of input and outputs can differ up to +/-10V. Opening any output loop does not affect 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 10-48 Vdc or 12-32 Vac. 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. CE, RoHS, ETL (UL 61010-1) certified.
