MOBILTEX uGI1-S Remote Rectifier Interruption

Combines GPS Location With Two-way Satellite Communication to Provide Precise Synchronization, Timing Accuracy And Repeatability For Rectifier Interruption.


In a matter of minutes field technicians can easily and permanently equip a cathodic protection rectifier with the advanced Mobiltex uGI1-S interrupter and upgrade the unit with remote monitoring and control for survey activities.

This small, high-performance device combines GPS location with two-way satellite communication to provide precise synchronization, timing accuracy and repeatability for rectifier interruption.

The addition of an optional Mobiltex Smart Relay cost-effectively expands the capabilities of the uGI1-S to include continuous monitoring of AC and/or DC load current, synchronization status, relay temperature and other important data that is logged by the interrupter.


Key Benefits

  • Two-way satellite transceiver enables remote control via CorView portal for interruption parameters and operation
  • Remote alarm reporting of fault conditions to enable rapid response
  • Precise timing and event data logging – includes geolocation, interruption activities, interruption faults (fault and load current logging available with optional smart relay)
  • User configurable interruption profiles can be set via Bluetooth connection with Apple or Android app
  • Compact, weather-proof enclosure with magnetic mounting feet can be installed in minutes
  • Lightning, surge and overvoltage protection and broad operating temperature range (-30°F to +158°F)
