LAU 73.1

LAU 73.1 provides analog current output from weighing operations based on strain gauge load cells. It is pin
compatible with other members of the LAU family, (63.1) thus offering a selection of precision levels, speed and
cost.
All LAU’s are designed to be embedded into customers’ equipment, to be plugged into a Unit Adaptor or otherwise
integrated with a hosting device.

Product highlights

• Designed for any automatic or manual weighing device requiring speed AND precision*.
• Designed for electrically hostile environments, reliability and simplicity of operation.
• Simple and robust communications, with point to point transfer and several units paralled.
• Extremely easy to configure.
• Zero set, gain set and filter set take place as binary organized steps, accessed directly at the unit.
• Outstanding stability using quality components and binary set-up switches.
• EMC compliance in robustness and surge protection.
• IP40 steel enclosure.
• * Usually speed and precision counteract each other. LAU 63.1 is a breakthrough design in providing high precision at high speed.

Product qualities

Converts the output from a load cell over a wide range at high resolution and linearity.
Analog bi-polar voltage output, 0 or 4 to 20 mA (at 10V), from a single strain gauge load cell.
Accomodates the full 10V load cell supply.
With binary switches, precalibration (within 1/500) can be performed before or after installation.
The binary organised range of the zero bands, the gain settings and the 3 LP filters enable almost any demand setting.
Additional quality 20 turn Zero and Span pots for fine adjustments are available.
EMC compliance and surge protection provided by electrically robust shielding and T-filters at all pins.
Can be bolted on the side of a load cell or designed into a PCB etc.
Compatible with a unit adaptor for DIN rail mounting, providing a fuse and regular screw terminals.
