Digital electropneumatic positioner
C US
8792 Positioner SideControl • Compact and robust design
• Easy startup using tune function
• No internal air consumption in steady
condition
• Profibus DPV1 or DeviceNet (optional)
• Assembly acc. to IEC 534-6/VDI VDE
3845 or Remote
The robust and compact positioner is designed to standardisation acc. to Envelope Dimensions [mm] (see datasheet for details)
IEC 534-6 or VDI/VDE 3845 for assembly with linear and rotary actua-
tors. In addition, the remote version with the displacement position sensor B
can be combined with Bürkert process control valves. The digital electro- Standard version
pneumatic positioner SideControl can be operated with the usual current A B L
and voltage standard signals and can also be equipped with the Fieldbus L 31 81.9 171.1
interface PROBUS DPV1. Additionally to the digital graphic display the
valve opening is signalled by a mechanical indicator element.
