The EC4A impulse driver will control your Gents, Synchronome and similar Slave Clock

EC4A - Slave Clock Impulse Driver

A small circuit controlled by a crystal and micro-controller and giving either a 30 second or 60 second pulse to drive a slave clock in the absence of a Master Clock. Small enough to fit behind the clock.

The controller activates a relay at the desired interval. The clock can then be powered by a battery pack located in the back of the clock or by an external wired power supply if desired. It will come as a bare built circuit or in a plastic enclosure.

Features..

∆ 30 or 60 second pulse

∆ Variable Pulse width

∆ Pulse forward and hold to stop pulsing

∆ 1 hour DST Forward

∆ 1 hour DST Back

∆ Better than 0.4 sec per day accuracy

Available with plastic backing/mounting
plate or fully encased.

Comes with a lead for the coil connection
and batteries for the driver.
Driver board battery has a switch for accurate starting.

If you don't have your own power provision for the clock mechanism you will
also need one of the power systems.
