GPS-Syntakt

The GPS-Syntakt time switch is used for the synchronous switching of rectifiers, flanges and coupons for cathodic corrosion protection applications.
After once being synchronised, the switching cycle is maintained by the internal rechargeable battery when the device is not in operation and immediately available even after the time switch has been transported in an instrument car for several weeks.

GPS-Synchronisation

GPS-Syntakt resynchronises itself automatically every 2 hours via the connected GPS antenna and thereby guarantees continuous synchronous switching without time deviations.
The GPS reception quality and successful GPS synchronisation (during the last 24 h) are indicated by two-colour LED on the front panel.

External or Manual Synchronisation

Without a connected GPS antenna it is possible to externally synchronise via another time switch (“Master and Slave”) or manually via the corresponding push button.

High Precision Quartz with continuous Temperatur Compensation

Being equipped with a highly precise and continuously temperature stabilised quartz time base the GPS-Syntakt enables synchronous switching for several weeks without resynchronisation.
This high sophisticated temperature compensation is unique for CP time switches.

Battery or Mains Operation

During GPS-operation the internal lead-acid battery allows mains-independent synchronous switching for more than 6 weeks. During mains operation the internal battery is automatically charged, and the installed charging electronics monitor the charge state.

Night and Weekend Suspend

It is possible to suspend the switching operation during the night and on weekends via a programmable LCD clock display installed on the front panel in order to maximise the protective current for the pipeline.

Secondary Switching with Relay or
Primary Switching Mains

Via its two potential-free pole terminals the internal relay of GPS-Syntakt has a maximum contact capacity of 15A / 60V. During 230V mains operation a primary switching of rectifiers with 230V / 6A is also possible via the installed grounding receptacle.

Optional: 
Electronic Relay (18A) 

The GPS-Syntakt variant with electronic 18A relay got no mechanical wear for the relay contacts.
When connecting the pole terminals there is no need to care for the polarity, as needed for other switcher with electronic relay.
This feature allows switching of pipe sections with AC interference.

Connection of External Slave Relays

To increase the switching power, an external slave relay can be additionally connected when the time switch is mains-operated. The mechanical slave relay permits switching of up to 60A and the electronic variants up to 100A.
