Construction
The GEMU 1235/1236 electrical position indicator is a microprocessor controlled programmable intelligent position indicator with an integral electronic travel sensor system (stroke). Optical position indication is made by LED and electrical position indication by relay with galvanically separated switch outputs. The housing cover is made of corrosion resistant plastic and the base is either PVDF (GEMU 1235) or stainless steel (GEMU 1236) with sealing to IP 67.

Features
  • For linear actuators with max. 75 mm stroke
  • Can be used for Normally open, Normally closed and Double acting valves
  • Option: field bus connection (AS-Interface)
  • Option: external programming input
Advantages
  • Standard OPEN and CLOSED feedback
  • speed-AP function, for quick mounting and initialisation
  • Quick cable connection
  • Easy to fit
  • Easy to use
  • Can be retrofitted to GEMU valves
  • Wide supply voltage range
