 t‘s a red-y smart
The pressure controllers combine the innovative equipment design of the red-y smart series with the development competence of Vögtlin Instruments AG.
High-quality components ensure long and trouble-free operation.

Analog & Digital

The pressure controllers make use of the latest CMOS technology and have a digital (Modbus RTU) and analog interface as standard*.

Profibus interface is available as option (Profibus DP-V0/DP-V1).

* analog output for actual value flow only


Operating Status Indication

The instruments offer a built-in LED status indication
