The QLPI731 is a four channel loop powered isolator that combines signal isolation and conversion in one compact package. Due to its width of only 15mm per channel and the 35mm DIN-Rail mounting the QLPI731 is an a "space saver" in larger control cabinets.

The base unit features selectable process inputs, range changing is achieved using internal solder pads.

Standard output is 4 - 20mA with a wide supply range of 7.5 to 38Vdc enabling 12V battery supply in automotive applications.

Double surge protection is standard with all series 700 loop powered transmitters to prevent failure due to spikes induced by

DC switched inductive loads. Final calibration is trimmed using internal zero and span trim adjustments. Front mounted LEDs verify the function of each channel.
