Installation / Time Control Technique
MULTITIMER
Multifunction relay
RK 7817

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 timer is suitable to realize flexible, time depending
controls in industry and building automation.
