Type 8791 – Digital electropneumatic Positioner SideControl

Type Description
The robust and compact positioner is designed to a standardisation acc. to IEC 65034-6-1 or VDI/VDE 3845 (IEC 60534-6-2) 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…20mA or by bus as an option. In addition there is a binary input and an optional analogue feedback available. The valve opening is signalled by a mechanical indicator element and the device status is shown on three coloured 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: – Close tight function – Inversion of the operating direction of the setpoint signal – Characteristic curves selection – Switching between manual and automatic mode. Additional possibilities on configuration and parameter setting, for example, linearisation of the operation characteristics by using communications 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.
