Advantages

  • Up to 10 functions in one unit
  • Simplified storage
  • Increased flexibility
  • Quick setting of long time values

Features

  • According to IEC/EN 61 812-1
  • 8 functions settable via rotational switch:
    - Delay on energisation (AV)
    - Fleeting on make (EW)
    - Delayed pulse (IE)
    - Flasher, start with pulse (BI)
    - Delay on de-energisation (RV)
    - Pulse forming function (IF)
    - Fleeting on break (AW)
    - Delay on energisation and de-energisation (AV / RV)
  • 8 time ranges from 0.02 s to 300 h selectable via rotational switches
  • Voltage range AC/DC 12 ... 240 V
  • With time interruption / time adding input for all functions
  • Suitable for 2-wire proximity sensor control
  • 2 changeover contacts, one programmable as instantaneous contact
  • LED indicators for operation, contact position and time delay
  • Wire connection: also 2 x 1.5 mm2 stranded ferruled, or 2 x 2.5 mm2 solid DIN 46 228-1/-2/-3/-4
  • as option with pluggable terminal blocks for easy exchange of devices
    - with screw terminals
    - or with cage clamp terminals
  • 22.5 mm width
  • MK 7850N/500: as MK 7850N/200 but with
  • 2 additional functions:
    - Cyclic timer, start with break (TP)
    - Fleeting on make and break (EW / AW)
  • second time setting t2 for functions
    - Cyclic timer, start with pulse (TI) or break (TP), based on the separate setting of pulse and break time the flasher function can be used as cyclic timer
    - Fleeting on make and break (EW/AW)
    - Delay on energisation and de-energisation (AV / RV)
    - Delay pulse (IE) and setting of pulse length
  • Connection facility for 2 external potentiometers
