Best Suited For:
  • Telecom

A stand-alone intelligent site controller that remotely monitors equipment and environmental conditions on the telecom site, simplifying maintenance and site management.

The EnergyMaster DPU is a standalone data processing unit. It provides remote monitoring for control of energy equipment and environmental control of telecom site with its powerful functionality, facilitating easy maintenance and management of a site.

The DPU not only provides common analog/digital inputs and outputs, but also provides AC/ Diesel monitoring via SM AC, battery monitoring via SM BAT and a large number of generic I/O via SM IO. Moreover, the DPU can communicate with Emerson or 3rd party intelligent equipment via its serial port, which will improve its monitoring capabilities for intelligent equipment.

If maintenance and site visits, related to the telecom site, are based upon this information they can be optimized to save both time and money, especially if the site is located remotely. The information and alarms, from a specific site, can be monitored or checked by means of a simple web browser or special monitoring software. When using a web browser no additional software is needed and the login to monitor the site is password protected.

The DPU is a supervision and control unit designed for global use, achieving high telecom standards, and providing great flexibility and expandability.
