Setting If the function switch is altered during operation, the new setting is valid immediately (like a restart of the relay). A new adjustment of the time or time range is also immediately valid. Please note, that a change of function, time range or time setting during elapse of time can lead to unintended switching of the output contacts. Adjustment assistance The flashing period of the yellow LED is 1 s ± 4 % and can be used to adjust the time. Especially on the lower end of scale and for long times it is suitable as the multiplication factors between the different time ranges are exact...

MULTITIMER Multifunction relay RK 7817 DOLD Product Description The multifunction timers RK 7817 in compact stepped front enclosures fulfills all the demands to modern time control devices. It completes the RK- timer range that covers with only a few single function variants all common timing functions, time ranges and voltage models. The MULTITIMER offers 8 functions, simply selectable via rotary switch and time ranges between 0.02 s and 300h. Besides the standard 1 c/o contact also a second c/o contact or an instantaneous c/o contact is available as option. Therefore this multifunction...
