Time control technique Multifunction relay MK 7850N/200 multitimer 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 Adjustment aid for quick setting of long time values Suitable for 2-wire proximity sensor control MK 7850N/200 2 changeover contacts, one programmable as instantaneous contact LED indicators for operation, contact position and time delay 2 Wire connection: also 2 x 1.5 mm stranded ferruled, or Options with plugable terminal blocks 2 2 x 2.5 mm solid DIN 46 228-1/-2/-3/-4 as option with plugable 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 Terminal block 2 additional functions: with cage clamp terminals - Cyclic timer, start with break (TP) (PC / plugin cageclamp) - Fleeting on make and break (EW / AW) second time setting t for functions 2 - 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 MK N P Terminal block Approvals and marking with screw terminals (PS / plugin screw) * Notes Canada / USA * see variants Removing the terminal blocks with cage clamp terminals Application 1. The unit has to be disconnected. Time-dependent controllers 2. Insert a screwdriver in the side recess of the front plate. 3. Turn the screwdriver to the right and left. Indicators 4. Please note that the terminal blocks can only be mounted on the belonging plug in terminations. green LED: on when voltage connected yellow LEDR/: shows status of output relay and time delay: -Continuously off: output relay not active no time delay -Continuously on: output relay active no time delay -Flashing (short on, long off) output relay not active time delay -Flashing (long on, short off) output relay active time delay All technical data in this list relate to the state at the moment of edition.
