MK7850N/200 多功能时间继电器，具有8种功能通过旋转开关可以调节，并且有8个时间范围从0/.02s到300h之间可调，主要应用于时间独立控制方面。

Multi-function relay MK 7850N/200 – multitimer

• According to 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 ... 300 h adjustable on rotational switches

• Voltage range AC/DC 12 ... 240 V

• With time interruption/time adding input

• Adjustment aid for quick setting of long time values

• Suitable for 2-wire proximity sensor control

• LED indicators for voltage supply, contact position and time delay

• Width 22.5 mm



• 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)

• With 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 (E
