概述
Area of application
數(shù)字量輸出模塊用于從控制器向過程變量輸出數(shù)字量信號。數(shù)字量輸出模塊把 S7-300 的內部信號電平轉換成過程所要求的外部信號電平。
用于連接電磁閥、接觸器、小功率電機、燈和電機啟動器。
Design
數(shù)字量輸出模塊具有下列機械特性:
具有8、16、32或64通道的模塊。
Functions
數(shù)字量輸出模塊將控制器的內部信號電平(邏輯“0”或“1”)轉換成過程所需的外部信號電平。
多種輸出電壓,可支持輸出不同的過程信號:
除了經濟性以及易于處理的特點外,該模塊還具有其他特殊功能:
數(shù)字量輸入模板用來實現(xiàn)PLC與數(shù)字量過程信號的連接。使用于連接標準開關和兩線制接近開關 (BERO)。
數(shù)字量輸入模塊具有下列機械特性:
具有8、16、32或64通道的模塊。
數(shù)字量輸入模塊將來自過程的外部數(shù)字信號電平轉換成控制器的內部信號電平(邏輯“0”或“1”)。
多種輸入電壓,可支持連接不同的控制信號:
除了經濟性以及易于處理的特點外,該模塊還具有其他特殊功能:
特殊模塊還可處理過程工程,例如支持 NAMUR 標準。
