SS5 Serie Bei Fehleranzeige Von Ventil Position Schützender Stellungsregler 4-20 mA

Eine tolle Kombination, smart Leistunssteller, wenn ein Fehler auftritt ermöglicht der Ventil eine Schutzposition.

Features

- "Fail Freeze" wenn die Funkiton die Elektrizität abschaltet sorgt der Kontrol Ventil die letzte Position zu behalten und informiert die Position.

- präzise und einfache automatische Kalibierung.

- Detecting RA (reverse acting) or DA (direct acting) automatically regardless of wrong air connections

- Available to use for single or double acting without any special adjustments

- Compact design allowing to be installed on small actuators

- Providing error messages against performance failures

- Possible to test the actuator with any fixed signal under a test mode

- Programmable characteristic curve with 17 points

- Es kann in einem weiten Temperaturbereich arbeiten: -30 ~ +80?

- Improved control of high-friction globe and ball valves by eliminating an overshoot and a hunting

- Low air consumption

- Providing a mounting bracket to meet IEC 60534-6-1 for linear valves

- Supporting a NAMUR mounting pattern VDI/VDE 3845 (IEC 60534-6-2) and providing a multi-size mounting bracket for rotary valves
