Wireless Current Loop Monitoring for
Process Instruments


When you combine the Telog iLR-32A current loop recorder and Telog Online, or Trimble Water Unity cloud solution, you have a powerful system of wireless water infrastructure monitoring that is consistently delivering real-time data from the field straight to your desktop. Imagine.....all your data on one platform straight to your computer screen.

Wireless Communication
The power of every 32 series recorder from Trimble Telog is wireless data transfer capability. Using cellular technology enables unmanned monitoring of remote sites as well as instant updates and alarm notifications. The iLR-32A uses a low power, LTE/Cat 1 cellular communication modem certified on Verizon Wireless. 

Collecting Data
The Telog iLR-32A may be configured to call its server application on a schedule (e.g. once per day; every four hours, etc.) and/or on alarm. Data may be stored in the recorder at user defined intervals (e.g. five minutes, one minute, etc.) without concern for data loss because the recorder will store over 82,000 interval totals before overwriting the oldest data.

The cellular modem, antenna, process signal conditioning, data recorder and battery are integrated into a small IP68 rated Nema 6P enclosure for a combined weight of 2.5 pounds and measuring 4”L x 4”W x 3”H [102mm L x 102mm W x 76mm H].

Battery Powered
Powered by a single user replaceable BP-4 lithium battery pack, the Telog iLR-32A continuously monitors the current loop (e.g. 4-20mA) output of a meter or process instrument in user defined time increments then transfers the data automatically over a cellular network to the cloud or to a central host computer. The Telog iLR-32A can operate up to five years making on average one call per day.

Software Support
The Telog iLR-32A is compatible with all Trimble software applications, including Trimble Unity, Telog Online (cloud), Telog Enterprise and Telogers for Windows application software. This ensures that utilities have a complete solution addressing all their remote monitoring requirements delivered in a manner that suits each individual utility’s operations and IT needs.
