產品簡介

美國RiceLake820i/820i-4B不僅是一款數字稱重顯示儀表，同時是一款為復雜自動化工業過程控制而設計、高性能可編程控制器

詳細介紹

美國Rice Lake 820i/820i-4B不僅是一款數字稱重顯示儀表，同時是一款為復雜自動化工業過程控制而設計、高性能可編程控制器。

稱重控制顯示儀表接受稱重傳感器輸出的模擬信號，經內部采集處理后，計算并顯示出秤體上物料的重量值。對秤體上物料的重量值與設定值的進行比較，如果重量值達到了設定值，控制器就輸出控制信號給執行設備。

稱重控制是集成了稱重和控制功能為一體的裝置，同時兼容工業現場總線，例如Modbus，可以和工業現場常用的控制器PLC，DCS等結合使用，方便工業領域的工程師解決工業稱重的問題。

Rice Lake's 820i is more than a digital weight display. It's also a high-powered programmable controller for automation of complex industrial processes.

For the most comprehensive combination of function and price, Rice Lake 820i is the instrument of choice. This versatile intelligent model boasts a powerful yet easy-to-use interface that can operate and display up to two scales simultaneously. The 820i allows users to automate formula selection, batch start up, data recall, or any frequently used process. Available in both universal and panel-mount versions.

Built-in software functionality includes programmability for alibi tracking, 25 definable print formats, and multi-range (interval). The RICELAKE 820i also conveniently stores up to 1,000 truck in/out records for recall at anytime and simplifies truck scale data management with six truck modes and keyed tares.
