PLC輸入輸出模塊是PLC與工業(yè)現(xiàn)場設備之間的核心連接橋梁，負責完成信號的雙向轉換與傳輸，是自動化控制系統(tǒng)里的關鍵組成部分。

一、核心作用

二、主流分類

按照信號類型和功能，可分為四大基礎類別：

1. ?數(shù)字量輸入模塊?：接收開關通斷類的二進制信號，常見支持24V DC或220V AC輸入，適配按鈕、行程開關等設備。

2. ?數(shù)字量輸出模塊?：分為繼電器型、晶體管型、晶閘管型三類：

3. 繼電器型：可驅動250V/2A交流負載，適合接觸器、電磁閥等設備，機械壽命約10萬次。

4. 晶體管型：響應速度可達0.1毫秒級，僅支持30V以下直流負載，適配高頻脈沖控制場景。

5. 晶閘管型：專為220V交流負載設計，無火花通斷，適合加熱管、交流電機控制。

6. ?模擬量輸入模塊?：采集溫度、壓力等連續(xù)變化的物理量，支持4-20mA、0-10V、熱電阻、熱電偶等信號格式。

7. ?模擬量輸出模塊?：輸出連續(xù)的電壓/電流信號，用于控制變頻器、比例調節(jié)閥等需要無級調節(jié)的設備。
