應用
這種信號調(diào)節(jié)器傳輸數(shù)字信號(NAMUR)傳感器/機械觸點)從現(xiàn)場到控制系統(tǒng)。接近傳感器或開關控制形式a正常打開負載繼電器觸點。正常輸出狀態(tài)為
使用開關S1反轉。開關S2允許輸出II在信號輸出和錯誤消息之間切換輸出。開關S3啟用或禁用線路故障檢測電路。
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鍵應用中切換狀態(tài)。
