Honeywell SC-UCMX01電源卡件模塊,SC-UCMX01使用數(shù)據(jù)
對(duì)于DCS接地系統(tǒng),其主要包括2方面作用:一方面,在信號(hào)、供電電源進(jìn)入DCS系統(tǒng)后或其自身發(fā)生故障時(shí),可以承擔(dān)超負(fù)荷電流而且能夠?qū)⑵鋫魅说刂校涣硪环矫妫拥叵到y(tǒng)可以提供屏蔽層給DCS,進(jìn)而隔絕電子噪聲干擾,SC-UCMX01同時(shí)可以提供參考零電位給全部系統(tǒng)。所以DCS系統(tǒng)通常包含工作及保護(hù)2個(gè)接地。DCS備件 在DCS控制系統(tǒng)的使用過程中,其管理工作是較為重要的。一般DCS備件管理的要求,概括就是四個(gè)方面:存放、檢查、使用準(zhǔn)備、使用。
1、 存放
DCS系統(tǒng)、備用模件存放應(yīng)滿足的要求為:各種模件必須用防靜電袋包裝后存放或根據(jù)制造廠的要求存放,模件存貯室的溫度、濕度也應(yīng)滿足制造廠的要求;存取模件時(shí)應(yīng)采取防靜電措施,禁止任何時(shí)候用手觸摸電路板,并且進(jìn)行登記,辦理進(jìn)、出庫手續(xù)。
2、 定期檢查
每半年對(duì)保存的各種少量常用DCS備件進(jìn)行檢查,當(dāng)然不同公司制定的周期不一樣,視實(shí)際情況而定,檢查內(nèi)容如下:
表面清潔、印刷板插件無油漬,印刷板插件無油漬,輕微敲擊后無異常;
裝入測(cè)試軟件,正常工作不少于48h以上;
冗余模件的切換試驗(yàn);
軟件裝卸試驗(yàn)正常,通信口、手操站工作正常;
各種模擬量、開關(guān)量輸入、輸出通道工作正常;
檢查后應(yīng)填寫檢查記錄,并粘上合格標(biāo)志。
3、 使用前準(zhǔn)備Honeywell SC-UCMX01電源卡件模塊
在運(yùn)行前必須檢查各通信口、I/O功能、控制算法功能是否滿足要求;在工程師站上對(duì)模件狀態(tài)進(jìn)行檢查符合要求;在模件內(nèi)裝入組態(tài),檢查是否正確。the electrical control system. Le PLC newly launched by Hollysys can not only realize complex logic control, high-precision analog quantity acquisition and processing functions, but also complete various sequential or timed closed-loop control functions, and has strong anti-interference ability, high reliability, small volume, simple programming, good openness and other functions, At the same time, Hollysys HMI is used to realize more intuitive monitoring and control. Through the application of this system, the user cost is greatly reduced, and the stability, accuracy and reliability in the control process are improved, so as to realize the economic, reasonable and efficient operation of the whole system. 2 principle and process equipment of resin continuous grinding machine can customize 9-head, 12 head, 14 head, 16 head and 20 head resin grinding disc continuous grinding machine according to the needs of users, and can also customize resin grinding
