Type 8791-Digital ElectroPneumatic Positioner SideControl

The robust and compact positioner is designed to a standardization acc. to IEC 534-6 or VDI/ VDE 3845 for assembly with linear and rotary actuators. In addition, the remote version with the displacement position sensor can be combined with Bürkert process control valves.

The setpoint setting for the electro-pneumatic digital Positioner SideControl BASIC occurs using a standard signal 4-20 mA or with AS-Interface as an option. In addition there is a binary input and an optional Analog feedback available.

The valve opening is signaled by a mechanical indicator element and the device status is shown on three colored LEDs. All the operational elements are found in the housing.

The start-up happens automatically, and directly at the device the following functions can be activated through DIP switches:

Additional possibilities on configuration and parameter setting, for example, linearization of the operation characteristics by using communications software which allows customized programming.

The pilot valve system can be used equally for single and double-acting drives. It is characterized by a defined safety feature in case of failure of the electrical or pneumatic power supply and possesses an enormous air capacity range with pressure supply up to 7 bar.
