PLY300 Batching Controller
Introduction
PLY300 batching controller is an intelligent instrument which is controlled by a single chip microcomputer and integrates weighing and control. The unique anti-interference measures enable the controller to be reliably used in harsh field environment. The controller can meet the needs of automatic batching in various industries such as construction, metallurgy, packaging, feed, etc. The instrument design is based on the relevant contents of the following standards: GB/T 7724-1999 weighing display controller.
