APPLICATION
Mercury 225 are data concentrator for data collection and transmission via the 0,4 kV power lines. The concentrator is the central node in PLC networks providing access to slave nodes from application programs. It performs meters network search, information packets routing, storage and transmission of data to the AMR/AMI system via a selected communication channel.
From technical point of view Mercury 225.11 and Mercury 225.21 concentrators are identical devices which differ only with embedded firmware implementing data transmission protocols of either PLC-I or PLC-II networks.
A module of three single-phase concentrators M225.11 or M225.21 is used in the three-phase network.
