PLC在20世紀90年代已經(jīng)形成微、小、中、大、巨型多種PLC。按I/O點數(shù)分，可分為微型PLC（32I/O）、小型PLC（256I/O）、中型PLC（1024I/O）、大型PLC（4.69I/O）、巨型PLC（8195I/O）五種。
PLC與工業(yè)生產過程的聯(lián)系是通過I/O接口模塊來實現(xiàn)的。PLC有許多I/O接口模塊，包括開關量輸入模塊、開關量輸出模塊、模擬量輸入模塊、模擬量輸出模塊以及其他一些特殊模塊，使用時應根據(jù)它們的特點進行選擇。
（一）確定I/O點數(shù)
根據(jù)控制系統(tǒng)的要求確定所需要的I/O點數(shù)時，應再增加10%～20%的備用量，以便隨時增加控制功能。對于一個控制對象，由于采用的控制方法不同或編程水平不同，I/O點數(shù)也應有所不同。表2列出了典型傳動設備及常用電氣元件所需的開關量的I/O點數(shù)。

（二）開關量I/O
開關量I/O接口可從傳感器和開關（如按鈕、限位開關等）及控制設備（如指示燈、報警器、電動機起動器等）接收信號。典型的交流輸入/輸出信號為24～240V，直流輸入/輸出信號為5～240V。盡管輸入電路因制造廠家不同而不同，但有些特性是相同的，如用于消除錯誤信號的抖動電路等。此外，大多數(shù)輸入電路在高壓電源輸入和接口電路的控制邏輯部分之間都設有可選的隔離電路。在評估離散輸出時，應考慮熔絲、瞬時浪涌保護和電源與邏輯電路間的隔離電路。熔絲電路也許在開始時花費較多，但可能比在外部安裝熔絲耗資要少。
