安全門模塊
安全門模塊適用于所有帶移動保護裝置(例如安全們)的場合。這類場合通常是需要進入正在工作的機器周圍，然后需要一個監控現場安全狀態的模塊來確保人身安全。
安全門模塊
符合安全等級4級
采用“與非門”方式檢測到線路故障或者斷線 (通過NO和NC觸點的組合).
通過模型使安全位置開關根據不同的時間差來監控
安全開關
安全開關也可看作是磁簧開關或帶半導體輸出。它們包括一個執行器和一個編碼傳感器。執行器帶磁性編碼，當傳感器感應到執行器的磁編碼時，執行器驅動觸點動作。
多德的安全開關NE5020有一個交叉故障檢測功能。當故障發生時，為安全起見評估器的輸出觸點切斷觸點，這樣可以防止重新啟動。安全開關有短路電流保護功能，并防止脈沖電壓的干擾。
