Pulse generator gets old clock ticking again!
Breng een oude fabrieks- of stationsklok weer tot leven met een pulsgever.
Vroeger werden deze zogenaamde dochterklokken centraal aangestuurd door een masterklok. Wij hebben een stukje elektronica ontwikkeld die de pulsen van een moederklok geeft, maar dan in klein.
Pulse generator gets old clock ticking again!
Installation
In this video, we demonstrate how to connect a pulse generator.
Installation is easy. We provide a manual, mounting material, connection terminals, and a battery box with the package.
The dimensions of the pulse generator are approximately 65 x 40 x 20 mm (LxWxH).
The battery box measures 70 x 65 x 20 mm (LxWxH)
We zijn overgestapt op een batterijdoos zonder deksel, in de video is de oude met deksel nog te zien.
The different pulse drivers
12/24V pulse driver
55mA pulse driver
Suitable for electric slave clocks from the French manufacturers Brillié (Electrique Brillié) ATO Charvet-Delorme
220mA pulse driver
300mA pulse driver
Suitable for slave clocks from English clockmakers Synchronome, E.C.S., and Smiths
What time is it?

Meet us at the fair!
Dit is de enige beurs voor elektrische klokken in Nederland, en de grootste in Europa. Met doorgaans meer dan 15 aanbieders met honderden elektrische klokken van de periode 1850 tot nu. De beurs is druk bezocht door bezoekers uit Nederland en omringende landen.
Everyone is welcome to attend. There will be experts present who can advise you if you are considering purchasing an electric clock. They can also provide more information about a clock you may already own.
Admission is free for visitors.
Pulse generator, master clock, slave clock - how does it work?
Lets go back in time!
From the year 1850 onwards, there was a lot of experimentation with electricity. New knowledge about electromagnetism was emerging, and the first batteries were invented. Could a clock also work with electricity? Of course, that was also extensively tested.
Rails began connecting cities and trains started running. Through the electric telegraph, messages could reach people elsewhere. Both greatly accelerated the arrival of the electric clock.
However, for many years, the basis for precise timekeeping remained the mechanical pendulum clock. And so, the master clock made its entrance. One expensive and very precisely calibrated mechanical clock for the exact time, but electricity for its distribution.
With the addition of electricity, one master clock could make a whole series of slave clocks display the correct time.
The pulses on which all slave clocks move the hands are given by the master clock once every 30 or 60 seconds. The master clock itself runs on the second.
The signal that the master clock sends to the slave clocks via copper wire is an electrical pulse. The pulses are a time indication: the minute starts now. At the same time, they contain the energy to move the clock hands. Therefore, we have named our device, which can control a slave clock, a pulse driver
Note: A daughter clock has different names, they are also called slave clock or pulse clock. A mother clock is also called a master clock (from English) or a main clock (from the German “Hauptuhr”)
A coil, magnet, and electric current
The presence of a coil is a typical and essential characteristic of an electric slave clock. Recognize the coil, and it is immediately clear that it is a slave clock. One or two coils can be found in any clock mechanism.
Where there is a coil, there is a magnet. However, the magnet gets smaller as the clock gets newer. So, it became increasingly difficult to identify the magnet, but it is certainly always present.
The coil
A coil is nothing more than a cylinder of wound copper wire. By passing a current through it, an electromagnetic field is generated. Like magnetic poles repel each other, while unlike poles attract. This allows a magnet placed in the field of the coil to move. These properties are used in timepieces to convert electrical energy into mechanical force and move the hands.
So simple, yet so beautiful!
Note: No visible coil of wound copper wire? A coil is often wrapped in a protective casing. This has the additional advantage that the manufacturer can put some (technical) information on it. For example, how many turns of wire it contains, or for which voltage the coil is intended.
