SPS 2023 - Produktvorstellung und Impressionen

Dec 2023 Interface Technology | Company

Nach Jahren intensiver Entwicklung in anspruchsvollen Bahnprojekten bringen wir unsere sicherheitsgerichteten Messtechniklösungen jetzt auch in die Automatisierungstechnik. Auf der SPS 2023 haben wir diese Produkte erstmals einem breiteren Fachpublikum vorgestellt – und möchten Ihnen heute mit einem kompakten Video die Highlights zeigen.

Von der Bahntechnik in die Automatisierung: Hochsichere Lösungen für neue Anwendungen

In unserem Video präsentieren zwei unserer Fachleute zwei zentrale Produkte, die ursprünglich für den Einsatz im Bahnbereich entwickelt wurden und nun auch in industriellen Automatisierungsanwendungen neue Standards setzen:

P45000 – Hochspannungstrennverstärker
Für Gleich- und Wechselspannungen bis 4500 V DC und 3000 V AC – inklusive funktionaler Sicherheit bis SIL 2/SIL 3. Perfekt für Anwendungen, in denen Sicherheit, Präzision und Kompaktheit gefragt sind.
P16800– Speed-Signal-Doubler
Mit innovativer, funktional sicherer Signalverarbeitung – SIL 4 bei der Signalentkopplung, SIL 2 bei der Übertragung von Encodersignalen. Die Lösung für anspruchsvolle Geschwindigkeitsmessungen, auch in sicherheitsrelevanten Systemen.

Auf dem SPS Forum referierte unser Kollege Martin Zierer über das Thema Funktionale Sicherheit und erläuterte dabei die Bedeutung des Live-Zero-Signals, auch Offset-Zero-Signal genannt.Bei einem Live-Zero-Signal, wie dem weit verbreiteten 4-20 mA-Standard, entspricht der kleinste Messwert nicht null, sondern einem definierten Offset-Wert – in diesem Fall 4 mA. Diese Offset-Verschiebung ermöglicht es, Fehlerzustände wie Kabelbrüche oder Sensorausfälle zuverlässig zu erkennen: Fällt der Signalstrom unter den definierten Mindestwert, kann dies als Hinweis auf einen Fehler interpretiert werden und erhöht die Zuverlässigkeit und Sicherheit von Messsystemen.
