GE's On-Site Network is a wide-area, wireless system designed to provide remote alarm monitoring, data acquisition and control. For monitoring a small number of remote sites in a local area or for consolidating the status of thousands of sites over entire regions, our On-Site Network is a comprehensive, yet cost-effective solution. The rugged Cellular Remote Terminal Unit (CRTU-6) supports six channels with a complement of inputs and a remotely controlled output that are suitable for virtually any monitoring and control application.
