An Easy Upgrade for Remote 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.

Fully functional interruption featuresTwo-way satellite transceiver enables remote control via CorView portal for interruption parameters and operation
Near real-time interactionsRemote alarm reporting of fault conditions to enable rapid response
Accurate and complete reporting Precise timing and event data logging – includes geolocation, interruption activities, interruption faults (fault and load current logging available with optional smart relay)

Frequently asked questions

What is the difference between the uGI1-B (Basic) and uGI1-S (Advanced)?

uGI1-B (Basic)
This is the GPS synchronized portable interrupter that can be configured locally with a Bluetooth enabled mobile device.

uGI1-S (Advanced)
This is the remote GPS synchronized portable interrupter equipped with two-way Iridium satellite communication. The uGI1-S can either be configured locally or sent commands with interruption parameters remotely via CorView.

How do I select the interruption profile I want on the uGI1?

Press the PROFILE “SEL” button next to the LCD on the underside of the uGI1.

How do I power the uGI1?

Attach the SRL1 AC/DC Smart Relay, SRL2 DC Smart Relay or the External Relay Interface cable to the uGI1, and connect the two yellow wires to a suitable voltage source. The acceptable input voltage range is 8VDC to 52VDC or 6VAC to 36VAC.
