MT-652, Telemetry Module for Cathodic Corrosion Protection Systems

MT-652, Telemetry Module for Cathodic Corrosion Protection Systems

MT-652 telemetry module provides compact and high specification solution for remote monitoring and controlling of pipeline cathodic protection systems, tanks and other metal structures buried in the ground or submerged in water. The flexibility of module configuration allows you to adjust it to a series of installations - from the simplest to the most complex. Internal resources of the device allow for easy and secure remote configuration and implemented data protection mechanisms ensure safe operation of the system. MT-652 module is dedicated to the system where power lines are not available.

The module comes with free software that uns on Microsoft Windows. It enables local configuration, remote configuration and includes an OPC driver that enables integration in SCADA systems.
