Product description

The MK 7830N is the ideal timer for timing control functions in industry and combines two separately configurable multifunction time relays in a housing that is just 22.5 mm wide. The simple and userfriendly configuration allows an optimised adaption to the application. The multifunction timer is also suitable for service and maintenance as it can replace timers with different functions and time ranges.
