Time dependent controls for industrial and railway applications
Features
- According to IEC/EN 61812-1
- 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
