1) plc晶體管輸出照應(yīng)快,可以用于高速輸出,但是控制電磁閥等仍是需求加中心繼電器;繼電器輸出照應(yīng)慢,但是可以省去外接繼電器,接線簡(jiǎn)略。具體選用什么輸出要視負(fù)載情況而定。2) 晶體管首要用于定位控制,要用晶體的輸出來宣告脈沖。而繼電器是不能用宣告脈沖的,也就不能定位控制了。如果用繼電器去控制定位伺服或是步進(jìn)的話就還要加定位模塊,經(jīng)濟(jì)上不劃算。而用一個(gè)晶體管輸出的就可以控制伺服等。就這么回事。依據(jù)

2) 晶體管首要用于定位控制,要用晶體的輸出來宣告脈沖。而繼電器是不能用宣告脈沖的,也就不能定位控制了。如果用繼電器去控制定位伺服或是步進(jìn)的話就還要加定位模塊,經(jīng)濟(jì)上不劃算。而用一個(gè)晶體管輸出的就可以控制伺服等。就這么回事。依據(jù)生產(chǎn)工藝要求,各種指示燈、變頻器/數(shù)字直流調(diào)速器的發(fā)動(dòng)中止應(yīng)選用晶體管輸出,它適應(yīng)于高頻動(dòng)作,而且照應(yīng)時(shí)間短;如果PLC體系輸出頻率為每分鐘6次以下,應(yīng)首選繼電器輸出,選用這種辦法,輸出電路的規(guī)劃簡(jiǎn)略,抗干擾和帶負(fù)載才干強(qiáng)。
細(xì)分:
1) 負(fù)載電壓、電流類型不同
負(fù)載類型:晶體管只能帶直流負(fù)載,而繼電器帶交、直流負(fù)載均可。電流:晶體管電流0.1A-0.5A,繼電器3A。電壓:晶體管可接直流24V一般最大在直流30V左右,繼電器可以接直流24V或交流220V。
2) 負(fù)載才干不同
晶體管帶負(fù)載的才干小于繼電器帶負(fù)載的才干,用晶體管時(shí),有 時(shí)分要加其他東西來帶動(dòng)大負(fù)載(如繼電器,固態(tài)繼電器等)。
3) 晶體管過載才干小于繼電器
過載的才干一般來說,存在沖擊電流較大的情況時(shí)(例如燈泡、理性負(fù)載等),晶體管過載才干較小,需求降額更多。
4) 晶體管照應(yīng)速度快于繼電器
繼電器輸出型原理是CPU驅(qū)動(dòng)繼電器線圈,令觸點(diǎn)吸合,使外部電源通過閉合的觸點(diǎn)驅(qū)動(dòng)外部負(fù)載,其開路漏電流為零,照應(yīng)時(shí)間慢(約10ms)。 晶體管輸出型原理是CPU通過光耦合使晶體管通斷,以控制外部直流負(fù)載,照應(yīng)時(shí)間快(約0.2ms甚至更?。>w管輸出一般用于高速輸出,如伺服/步進(jìn)等,用于動(dòng)作頻率高的輸出。
5) 在額外作業(yè)情況下,繼電器有動(dòng)作次數(shù)壽數(shù),晶體管只需老化沒有運(yùn)用次數(shù)
束縛繼電器是機(jī)械元件所以有動(dòng)作壽數(shù),晶體管是電子元件,只需老化,沒有運(yùn)用次數(shù)束縛。繼電器的每分鐘開關(guān)次數(shù)也是有束縛的,而晶體管則沒有。
