The robust and compact positioner is designed to a standardisation 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 com-bined with Bürkert process control valves The setpoint setting for the electropneumatic 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 analogue feedback available. The valve opening is signalled by a mechani-cal indicator element and the device status is shown on three coloured LEDs. All the opera-tional elements are found in the housing. The start-up happens automatically, and directly at the device the following functions can be acti-vated through DIP switches:

- Close tight function- Inversion of the operating direction of the

setpoint signal - Characteristic curves selection- Switching - manual and automatic operation

Additional possibilities on configuration and parameter setting, for example, linearisation of the operation characteristics by using com-munications software which allows customised programming. The pilot valve system can be used equally for single and double-acting drives. It is characterised 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.
