YOUR TOUGHEST TRANSIENT CURRENT DIAGNOSIS CHALLENGES ARE SOLVED with full RMU1 capabilities and enhanced fast sample datalogging

Introducing the CorTalk RDL1

The CorTalk RDL1 represents a convergence of two classes of technology that have long been cornerstones of the Cathodic Protection industry – stationary dataloggers and remote monitoring units. In a significant evolutionary step, the RDL1 is the industry’s most powerful and versatile battery powered remote monitoring device with enhanced fast sample datalogging capabilities.

Combining the best elements of both technology classes, the RDL1 allows operators to gain visibility into the performance and state of their protection systems while capturing high volumes of data directly to the CorView Cloud Platform via CAT-M1 [LTE-M 4G/5G] cellular connections that are granular enough for forensic and diagnostic analysis. A versatile tool, the RDL1 can be used in a wide range of applications; from identifying dynamic AC and DC interference from a light rail transit system, to being used for datalogging Telluric impacts during a survey, to monitoring a Constant Potential Rectifier.

In addition, the RDL1 pairs with the CorTalk INT1 to provide GPS synchronized interruption for critical bonds and sacrificial anodes, eliminating the need for technicians to install portable interrupters. Simply put, the CorTalk RDL1 represents a new generation of remote monitoring capabilities that will dramatically improve how CP systems are operated.

Dual Data File StructureIndividual RMU Readings + Fast Sample Recording – promotes efficiency for battery life and data plan structure
Fast Sample FunctionalityScheduled or Event-based, from 10S sampling to 0.1S sampling (limited to 3hr max per day)
Smart, simple installationThe compact, weather-proof RDL1 is designed to fit entirely inside a standard CP test station [external antennas optional] and can be installed in about 20 minutes
Engineered for expandable functionalityRDL1 platform allows connection of additional external accessory modules like the INT1 for GPS synchronized interruption and a 4-20mA Mode [United States Patent US-11753729-B2]
Multiple pre-defined configurationsThe RDL1 can be wired for single coupon, dual coupon, separate AC and DC coupons, and bond monitoring applications including reverse current switches
Intuitive controls and configurationsThe RDL1 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
Future-proof communication capabilitiesAvailable with CAT-M1 cellular [LTE-M – 4G/5G compatible] communication technology – improving the quality and frequency of data collection while reducing the need for workers to visit remote or hazardous site locations. **Iridium Satellite is under development
