Multifunction relay RK 7817 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 timer is suitable to realize flexible, time depending controls in industry and building automation. Advantages .
