NeXGen GCU Remote Terminal Unit Product Page


Ultra Low Power Remote Terminal Unit


The Telescada NeXGen™  GCU Remote Terminal Unit is a powerful, flexible an economical solution for distribution automation, monitoring, alarming and control.  Built upon a modular and expandable framework, the NeXGen™  GCU meets the needs of distribution engineers for the monitoring and control of new distribution facilities or the upgrade of existing ones. In fully functioning analog sampling operation the  NeXGen™  GCU draws only 10mA of current, making the  NeXGen™  GCU a excellent instrument for the monitoring and control of remote assets that are subject to power outages and interruption wherein the  NeXGen™  GCU needs to remain functional for a long period on battery back up power

The NeXGen™  GCU’s flexible design provides users with an I/O core of 4 configurable analog inputs, 8 digital status inputs and 3 control outputs. The NeXGen™  GCU can be expanded to add additional I/O though the networking of additional NeXGen™ modules. The NeXGen™ is an addressable distributed RTU that can be quickly expanded to meet the specific requirements of the user In additional to configurable I/O the NeXGen™  GCU serves to consolidate and transmit data from a network of IEDs (intelligent electronic devices) via its RS-232 and RS-485 serial communications links. RS-232 remote communications ports allow for remote data transmission via radio, dial-up, cellular or fiberoptic tranceivers

A local maintenance port allows for direct interrogation and programming of the NeXGen™  GCU using the NeXGen™ NGC Maintenance Utility Software. DNP3.0 standard communications protocol allows the NeXGen™  GCU to communicate with any modern SCADA system. The NeXGen™ GCU core’s small footprint allows for quick installation on distribution panels, or mounting within a wall mount or pole top enclosure. The NeXGen™ GCU supports multiple input voltages, and complete NeXGen™ GCU, power and communications packages are available from Telescada.
