Construction
The digital electro-pneumatic positioner detects the valve position with an external LongLife travel sensor. It has a solid housing with protected operating keys and an easy to read LCD display. The operating times can be set by integrated throttles. Connection and mounting to NAMUR is also possible.

Features
  • Simple and self-explanatory menu
  • Automatic initialisation function
  • Safety function during power or compressed air supply failure
  • Protection class IP 65
  • 3/4-wire type
  • Can be used with linear and quarter turn actuators
  • Operation with single and double acting actuators
Advantages
  • Separate mounting of positioner and travel sensor
  • Simple handling and commissioning
  • Simple electrical connection by detachable terminals
  • Automatic optimization of valve control during initialisation
  • No air consumption when idle
