二、輸出回路的規(guī)劃
1、各種輸出辦法之間的對(duì)比
(1)繼電器輸出:
長(zhǎng)處是不一樣公共點(diǎn)之間可帶不一樣的交、直流負(fù)載,且電壓也可不一樣,帶負(fù)載電流可達(dá)2A/點(diǎn);但繼電器輸出辦法不適用于高頻動(dòng)作的負(fù)載,這是由繼電器的壽數(shù)決 定的。其壽數(shù)隨帶負(fù)載電流的添加而削減,通常在幾十萬(wàn)次至Jl百萬(wàn)次之間,有的公司商品可達(dá)1000萬(wàn)次以上,呼應(yīng)時(shí)刻為10ms。
(2)晶閘管輸出:
帶負(fù)載才干為0.2A/點(diǎn),只能帶溝通負(fù)載,可習(xí)慣高頻動(dòng)作,呼應(yīng)時(shí)刻為1ms。
(3)晶體管輸出:
最大長(zhǎng)處是習(xí)慣于高頻動(dòng)作,呼應(yīng)時(shí)刻短,通常為0.2ms左右,但它只能帶 DC 5—30V的負(fù)載,最大輸出負(fù)載電流為0.5A/點(diǎn),但每4點(diǎn)不得大于0.8A。
當(dāng)你的體系輸出頻率為每分鐘6次以下時(shí),應(yīng)首選繼電器輸出,因其電路規(guī)劃簡(jiǎn)略,抗干擾和帶負(fù)載才干強(qiáng)。當(dāng)頻率為10次/min以下時(shí),既可選用繼電器輸出辦法;也可選用PLC輸出驅(qū)動(dòng)達(dá)林頓三極管(5—10A),再驅(qū)動(dòng)負(fù)載,可大大減小。
2、抗干擾與外部互鎖當(dāng) PLC輸出帶理性負(fù)載,負(fù)載斷電時(shí)會(huì)對(duì)PLC的輸出構(gòu)成浪涌電流的沖擊,為此,對(duì)直流理性負(fù)載應(yīng)在其周?chē)⒔永m(xù)流二極管,對(duì)溝通理性負(fù)載應(yīng)并接浪涌吸收電 路,可有用保護(hù)PLC。當(dāng)兩個(gè)物理量的輸出在PLC內(nèi)部已進(jìn)行軟件互鎖后,在PLC的外部也應(yīng)進(jìn)行互鎖,以加強(qiáng)體系的牢靠性。
