Mains operated Timer Switch with Radio Signal Synchronisation

This radiosignal-synchronised timer switch has been designed for fixed installation.
Its miniaturised dimensions allow permanent installation on CP sites.
TELETAKT is a radiosignal-synchronised timer switch for cathodic protection. The unit receives time signals of station DCF 77 synchronising its own quartz-controlled time base by means of comparison and adjustment logics.
In case of externally caused disruption of reception of radio time signals, the unit’s internal quartz-time basis takes over synchronised pulse operation.
The electronic fieldstrength meter at the unit‘s front allows optimal positioning of rf antenna.
The timer switch features three selectable switching periods: 4/1, 12/3 and 27/3 s.
In addition the unit contains a switchable automatic radiosignal-controlled night-and weekend break facility preventing the protecting potential from getting positive caused by extensive switching intervals during long term measuring sessions of switching off potentials at ill polarized cathodic protection systems.
Night break periods between 19.00 and 07.00h as well as pulsing periods may be adjusted to customers‘ requirements.
Despite its small dimensions the unit contains a switched 230 V - 2.5 A thyristor relay output terminal, allowing higher currents to be switched by an external relay or contactor. The timer switch is being connected via 5 in-line terminals at the unit’s faceplate.
The mounting kit allows horizontal as well as vertical installation of the unit.
