Precisely Synchronized Rectifier Interruption

Small, powerful and easily installed, the Mobiltex uGI1-B enables field technicians to quickly equip rectifiers with interruption capabilities during periodic surveys of cathodic protection systems.

These tough, compact devices are designed to provide precise timing, repeatability and control of rectifier interruption and utilize GPS signals to synchronize operation with all uGI1 units. Event data is recorded by the unit and stored until field technicians download it via USB connection.

The addition of an optional Mobiltex Smart Relay cost-effectively expands the capabilities of the uGI1-B to include continuous logging of load current and interruption faults.

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)
Intuitive controls and configurationsEasily download data and upgrade firmware via USB connection. The uGI1-S can be easily programmed with our standard Programming Interface and a PC and can also be completed with a compatible iOS or Android-based mobile device and our available Bluetooth Interface.

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.
