Teletakt N

Mains operated Time Switch with Radiosignal Synchronisation

A cathodic protection system will only remain effective as long as it is permanently supervised. This necessitates regular check of on- and off-potentials. As usually several protecting areas border each other, therefore off-potential measurements need rectifiers with synchronously acting time switches.
TELETAKT-N is a time switch specially designed for the cathodic corrosion protection. This switcher receives time signals of the German radio station DCF 77 synchronising its own quartz-controlled time base by means of comparison and adjustment logic. In case of externally caused disruption of reception, the internal quartz time base takes over synchronised switch operation of the unit.
TELETAKT-N offers three different switching cycles: 4 / 2 s, 12 / 3 s and 27 / 3 s. The switching cycles may be modified against surcharge by the manufacturer in accordance to the specific request of the customers.
In addition the unit contains a switchable automatic radio signal controlled night and weekend break facility in order to minimise the decrease of the cathodic protection current. The standard night break period is between 19.00 and 07.00 h.
It is possible to switch higher currents up to 60 Ampere by means of different mechanical slave-relays (option) which are connected to the grounding-type attachment receptacle.
