1790D-TN0V2

福州聚福興自動化有限公司為您提供1790d-tn0v2。

1、采用---良的電源，電網引入的

在plc控制中，電源占有極重要的---。電網串入plc控制主要通過plc的供電電源如cpu 電源、i/o電源等、變送器供電電源和與plc具有直接電氣連接的儀表供電電源等耦合進入的。現在，對于plc供電的電源，一般都采用隔離性能電源，而對于變送器供電的電源和plc有直接電氣連接的儀表的供電電源，并沒受到足夠的，雖然采取了一定的隔離措施，但普遍還不夠，主要是使用的隔離變壓器分布參數大，能力差，經電源耦合而串入共模、差模。所以，對于變送器和共用儀表供電應選擇分布電容小、帶大如采用多次隔離和屏蔽及漏感技術的配電器，以plc的。

此外，位---電網饋點不中斷，可采用在線式不間電電源ups供電，供電的安全---性。并且ups還具有較強的隔離性能，是一種plc控制的電源。

2、電纜選擇的敖設

為了動力電纜輻射電磁，尤其是變頻裝置饋電電纜。筆者在某工程中，采用了銅帶鎧裝屏蔽電力電纜，從而了動力線生產的電磁，該工程投產后取得了滿意的效果。

不同類型的分別由不同電纜傳輸，電纜應按傳輸種類分層敖設，嚴禁用同一電纜的不同導線同時傳送動力電源和，避免線與動力電纜靠行敖設，以電磁。
