DOLD Multifunction relays MULTITIMER
Multifunctional relays are universally usable thanks to the selection of the corresponding function. They also belong to the group of time relays with which you can cost-effectively realised specific time functions. A multifunctional relay can be used as a flasher relay, clock, impulse former, start-up and/or shut-down relay as well as contact and recurrence delay. You can simply set the respective function on the device.

DOLD Fleeting action relays, pulse shaper, star delta timer MINITIMER
DOLD Fleeting action relays, pulse shaper, star delta timer MINITIMER
Machines and systems such as dosing systems and rinsing systems are where wiping relays are used. DOLD wiping relays are available as both input as well as output wiping relays. While the input wiping relays immediately switch the operating voltage to the work position after installation, output wiping relays are placed over the voltage control contact on the control input. If this is open, the relay immediately switches to the work position. Both relay types switch back to resting position immediately after the expiration of the set wiping time.

DOLD Flasher and cyclic timers MINITIMER
DOLD Flasher and cyclic timers MINITIMER
DOLD flasher relays are used on cranes, wind power systems as well as airfield lighting where they control position lighting. The control of malfunction notifications on machines, lighting, fans, et cetera is an additional task of these devices. Impulse time and pause time are identical with flasher relays.
Clocks from DOLD are important components of traffic light control systems, automatic ovens, et cetera. They have the same function as flasher relays with the difference that the impulse and pause times for time-dependent control systems are different from each other and can thus be set separately.

DOLD Timers on delayed MINITIMER
DOLD Timers on delayed MINITIMER
With contact delayed time relays, the start is triggered by the activation of the operating voltage. The relay switches to the work position after the expiration of the configured delay time. Contact delayed time relays from DOLD are used for forward switching, e.g. pre-heating, or for delay times in switching systems such as for the delayed activation of system parts in burner controls, escalators and elevators.

DOLD Timers off delay MINITIMER
DOLD Timers off delay MINITIMER
For time relays with recurrence delay, we distinguish between devices with and without auxiliary voltage. While devices without auxiliary voltage are only realizable for short times, those with auxiliary voltage are also suitable for longer periods of time. Repress delayed time relays from DOLD are used for follow-on switching (e.g. fans), lighting control systems (e.g. stairwell lighting) or for the delayed switching to an emergency power generator and/or an emergency lighting system.

Technical Information and Features

DOLD multifunction timer MK 7830N - perfect timing in all situations.

The compact multifunction timer MK 7830N of the MULTITIMER series combines many years of experience together with most modern time control technology. For the first time DOLD combines 2 multifunction timers in an enclosure with only 22.5 mm width. The small enclosure and the variety of functions offer a maximum of possibilities in a minimum of width. This saves space and cost. The multifunction timer with display has 2 output relays that can be configured independently from each other. The most simple and user friendly configuration allows optimised adoption to the application. Functions and time can be set separately in a range from 20 ms to 9999 h. On delay, pulse former, fleeting on make together with fleeting on break are only 3 out of 12 selectable functions. Because of the well designed concept with simple menu driven setting, together with a space saving, compact enclosure, the digital multifunction timer MK 7830N is the ideal timing component for control applications in all industries.

Your advantages:
- 2 independent adjustable multifunction relays in one enclosure
- Minimum width of 22.5 mm saves space and cost
- Highest precision at shortest but also at longest time settings
- Production results are reproducible when used in standard machines
- Simple and user friendly handling
- LCD display is good to read and with high contrast
- Different connection options
- No loss of setting parameters on power failure
- Always the right timer in stock.
DOLD multifunction timer MK 7830N - perfect timing in all situations.
