TM 345 M


  • Electronic time relay
  • Locking snap switch to select the period of time, as well as the following operating modes:
  • Response delay (AV), without control contact
  • Wipe contact (EW), without control contact
  • Release delay (RV), with control contact
  • Pulse former (IF), with control contact
  • Response and release delay (VZ), with control contact
  • Pulse output (WR), with control contact
  • Flip-flop (TG)
  • Can be used universally for controlling automatic processes in machines, lighting, ventilation, heating, cupboards etc.
  • Precise analogue time setting
  • Multi-voltage input for all supply and control voltages, no jumpers or additional terminals are required
  • LED to display the switching status
