8.1 Overview
This chapter describes the specifications for load cell modules, their operation, and their programming. You
can use the AS02LC load cell module with four-wire or six-wire load cells with various eigenvalues, so you
can adjust its response time according to your requirements. In addition, the AS02LC-A can read and write
data via the AS Series PLC units using the FROM/TO instructions. To ensure that the product is correctly
installed and operated, read the manual carefully before use. This manual provides functional specifications,
and it also introduces installation, basic operation, and settings. Refer to load cell related literature for more
details on the principles of operating load cells.
