輸出回路的設計
1、各種輸出方式之間的比較
（1）繼電器輸出：
優(yōu)點是不同公共點之間可帶不同的交、直流負載，且電壓也可不同，帶負載電流可達2A／點；但繼電器輸出方式不適用于高頻動作的負載，這是由繼電器的壽命決 定的。其壽命隨帶負載電流的增加而減少，一般在幾十萬次至Jl百萬次之間，有的公司產(chǎn)品可達1000萬次以上，響應時間為10ms。
（2）晶閘管輸出：
帶負載能力為0.2A/點，只能帶交流負載，可適應高頻動作，響應時間為1ms。
（3）晶體管輸出：
zui大優(yōu)點是適應于高頻動作，響應時間短，一般為0.2ms左右，但它只能帶 DC 5—30V的負載，zui大輸出負載電流為0．5A/點，但每4點不得大于0.8A。
當你的系統(tǒng)輸出頻率為每分鐘6次以下時，應*繼電器輸出，因其電路設計簡單，抗干擾和帶負載能力強。當頻率為10次／min以下時，既可采用繼電器輸出方式；也可采用PLC輸出驅動達林頓三極管（5—10A），再驅動負載，可大大減小。
2、抗干擾與外部互鎖當 PLC輸出帶感性負載，負載斷電時會對PLC的輸出造成浪涌電流的沖擊，為此，對直流感性負載應在其旁邊并接續(xù)流二極管，對交流感性負載應并接浪涌吸收電 路，可有效保護PLC。當兩個物理量的輸出在PLC內部已進行軟件互鎖后，在PLC的外部也應進行互鎖，以加強系統(tǒng)的可靠性。
3、“GOM“點的選擇不同的 PLC產(chǎn)品，其“COM”點的數(shù)量是不一樣的，有的一個“COM”點帶8個輸出點，有的帶4個輸出點，也有帶2個或1個輸出點的。當負載的種類多，且電流 大時，采用一個“COM”點帶1—2個輸出點的 PLC產(chǎn)品；當負載數(shù)量多而種類少時，采用一個“COM”點帶4—8個輸出點的PLC產(chǎn)品。這樣會對電路設計帶來很多方便，每個“COM”點處加一熔絲， 1—2個輸出時加2A的熔絲，4—8點輸出的加5—10A的熔絲，因 PLC內部一般沒有熔絲。
4、PLC外部驅動電路對于 PLC輸出不能直接帶動負載的情況下，必須在外部采用驅動電路：可以用三極管驅，也可以用固態(tài)繼電器或晶閘管電路驅動，同時應采用保護電路和浪涌吸收電 路，且每路有顯示二極管（LED）指示。印制板應做成插拔式，易于維修。
PLC的輸入輸出布線也有一定的要求，請看各公司的使用說明書。
