LX3V-2WT-L
1 WECON Technology Co., Ltd
1. Weighing module Operating principle
Electrical resistance of metal material changes in proportion to the forces being applied to deform it.
The strain gauge measures the deformation as a change in electrical resistance, which is a measure
of the strain and hence the applied forces (load).
2. Introduction
1) WECON LX3V-2WT-L expansion module’s resolution is 18-bit. The module can be used for
reading signals from 4- or 6- wire configuration;
2) Please read through the manual before powering on the module.
3) This manual is only applicable for model number: LX3V-2WT-L. Please double check the mark
on your module.
4) Using FROM/TO command to read/write data on PLC LX3X.
