The XCell RTU platform has been designed to facilitate the automation of T&D networks by collecting, processing and distributing data within the hostile electrical environment of MV and HV substations. The XCell RTU offers high performance with high availability supporting a range of redundancy options including multi-processors, redundant substation communications, dual power feed, and redundant communications to remote Control Centres. It offers a vast library of protocols including IEC101/104/103, DNP3 and IEC61850 to support most IEDs and Control Centre communications. Support for IEC61850 offers an integration platform for existing and future IEDs. The RTU offers extensive automation functions, including IEC61131 applications, ranging from simple to the most complex. The RTU architecture and modularity allow us to offer complete turnkey solutions for every customer`s requirements. A small low count RTU is also available using the Smart Controller / Distribution Automation Controller for low point count applications.
