4480 - Электропневматический позиционер. Чертеж
  • Compact metal housing
  • Graphic display with backlight
  • Easy start-up
  • Comprehensive range of additional software functions
  • Profibus DPV 1 (optional)
  • Assembly acc. to IEC 534-6 / VDI VDE 3845

The robust and compact positioner is designed to 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 combined with Burkert process control valves. The digital electropneumatic positioner SideControl can be operated with the usual current and voltage standard signals and can also be equipped with the fi eldbus interface PROBUS DPV1. Additionally to the digital graphic display the valve opening is signaled by a mechanical indicator element.

Operation occurs via the external operation and display module. It consists of a backlit graphical display and a robust ransparency keyboard with four keys with software driven function indication. For the user operation is very simple and clear, identical to the Burkert positioner or process controller TopControl, Type 8692/8693.

The pilot valve system can be used equally for single and double-acting drives. It is characterised by a defi ned 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.
