應用
這種隔離屏障用于內(nèi)在安全應用。它傳輸數(shù)字信號(NAMUR傳感器/機械)從危險區(qū)域到安全區(qū)域。接近傳感器或開關(guān)控制形式a正常為安全區(qū)域負載開繼電器觸點。正常的輸出可以使用開關(guān)S1和S2來反轉(zhuǎn)狀態(tài)。S3是切換用于啟用或禁用現(xiàn)場電路的線路故障檢測。在出現(xiàn)錯誤的情況下，繼電器恢復到斷電狀態(tài)根據(jù)NAMUR NE44，狀態(tài)和led指示故障。一個惟一的集體錯誤消息傳遞特性在什么時候可用與動力軌系統(tǒng)配套使用。由于其緊湊的外殼設計和低散熱，該裝置可用于檢測位置、端部停止和在空間關(guān)鍵應用中切換狀態(tài)。
