產(chǎn)品詳情
輸入/輸出信號(hào)的牢靠性是操控體系正常作業(yè)的基本條件,沒有牢靠的體系輸入/輸出信號(hào),再好的操控體系也無法正常作業(yè)。因?yàn)楦骷夹g(shù)段子體系較多,十分渙散且現(xiàn)場(chǎng)條件惡劣,其中現(xiàn)場(chǎng)信號(hào)遭到攪擾,致使繼電器無法正常作業(yè)即是十分棘手的疑問之一,因此,為確保設(shè)備正常作業(yè),其輸入/輸出信號(hào)繼電器的挑選即是關(guān)鍵所在。為處理以上疑問,馬鋼通過多方對(duì)比,最終選用PHOENIXCONTACT的PLC-RSC- 230UC/21/SO46、 PLC-RSC-230UC/21-21/SO46抗攪擾繼電器以及PLC-RSC-24DC/21、PLC-RSC-24DC/21直流繼電器。挑選PLC-RSC-230UC/21/SO46、 PLC-RSC-230UC/21-21/SO46抗攪擾繼電器的理由主要有兩點(diǎn):其一是該繼電器驅(qū)動(dòng)電流較大(通常為8mA左右)而且具有信號(hào)濾波功用,并選用RC 回路以及抬高繼電器的動(dòng)作電平來按捺攪擾信號(hào),其特別適用于現(xiàn)場(chǎng)檢查元件較遠(yuǎn),以及因?yàn)楝F(xiàn)場(chǎng)挨近開關(guān)或PLC模塊漏電流較大等因素致使普通繼電器難以正常作業(yè)的各種雜亂的工業(yè)操控現(xiàn)場(chǎng);第二是該繼電器為端子型繼電器,體積較小,可有用地節(jié)省裝置空間而且易于裝置和接線。馬鋼新區(qū)項(xiàng)目中,共運(yùn)用PHOENIXCONTACT的PLC系列繼電器30000多只,為現(xiàn)場(chǎng)開關(guān)量牢靠的輸入/輸出供給了有用確保。
