The products are mainly used in data acquisition, signal transmission and conversion, PLC, DCS and other industrial measurement and control systems in the fields of machinery, electricity, telecommunications, electric power, petroleum, chemical industry, iron and steel, sewage treatment, building construction and so on. They are used to improve and supplement the system analog I / O plug-in function and increase the applicability of the system and the reliability of the on-site environment.
YOKOGAWA(橫河)1975年率先研制出世界上*套具有劃時代意義的集散型控制系統(tǒng)(DCS系統(tǒng)),對石油、化工等大型工廠的生產(chǎn)過程進行測量、運行監(jiān)視和控制,為工業(yè)的發(fā)展和社會的進步做出了極大貢獻,到目前已相繼推出了7代CENTUM DCS系列產(chǎn)品,流量表、變送器、分析儀等現(xiàn)場儀表也得到了用戶的高度評價。
YOKOGAWA的計測技術事業(yè)核心--測量儀器事業(yè),有著高穩(wěn)定性和高可靠性的產(chǎn)品以及始終*于時代的計測技術,使之成為一個在世界上值得信賴的合作伙伴。通過與安藤電氣公司的合并,進一步擴大了通信測量儀器的生產(chǎn)領域。如今又將目光投向光通信,移動通信測試和數(shù)字式信息家電等領域,力爭在測量儀器方面成為*的生產(chǎn)廠家。
一、產(chǎn)品介紹:
EN83*A EN83*以太網(wǎng)網(wǎng)卡產(chǎn)品主要應用于機械、電氣、電信、電力、石油、化工、鋼鐵、污水處理、樓宇建筑等領域的數(shù)據(jù)采集、信號傳輸轉換、PLC、DCS等工業(yè)測控系統(tǒng),用來完善和補充系統(tǒng)模擬I/O插件功能,增加系統(tǒng)適用性和現(xiàn)場環(huán)境的可靠度。
