FieldConnex プロセスインターフェースは、複数の従来の入力と出力とをフィールドバスに最小ケーブルにてつなぎます。 本質安全防爆には以下が含まれます:センサとアキュレータはZone 0/ Div.1に取付け可能で、 プロセスインターフェースはZone1/ Div.1です。I/O は、フィールドバスにて給電されており、ケーブルが節約できます。プロセスインターフェースには、標準ファンクションブロックとフィールド機器の各種タイプをメーカから選択出来る柔軟性があります。
各入力は、個別にパラメータ化されています。TM-I は、冷接点と、センサおよび配線状況の監視もサポートします。
The FieldConnex® Multi-Input Output (MIO) provides connection for various disrcete signals to the DCS via fieldbus and one single address. The MIO monitors the status of up to twelve NAMUR sensors or controls up to four valves—including final position feedback and automated partial stroke test. Due to its integrated breakaway and runtime monitoring for valves, an alarm signal is emitted when limit values are exceeded. Alternatively, MIO enables overflow and idle level of containers and conduits monitored by vibration limit switches. All inputs and outputs of Multi-Input Output are intrinsically safe. The MIO serves the exact same functions as FieldConnex valve couplers and binary interfaces and as a drop-in replacement with no reconfiguration required at the PLC or DCS. New and unique is the frequency or pulse input for monitoring of rotating equipment.
