IEC 61850 Stand Alone Merging Units
IEC61850 Sampled Values as per the latest IEC61869-9 standard
IEC61850 19’’ SAMU for the substation building
The rack-mounted, 19’’ Stand Alone Merging Unit typically will be installed in a cabinet in the substation building. The incoming analog signals from the VTs and CTs will be connected to the 19’’ SAMU who will process them and send IEC61869-9 or IEC61850-9-2LE Sampled Values to the IEC 61850-9-2 Process Bus.
The 19’’ SAMU has a local display to ease commissioning and maintenance works.
The 19’’ SAMU supports 1PPS and IEEE1588 synchronization for time-stamping the Sampled Values.
The 19’’ SAMU supports both PRP and HSR that allow redundancy in the communication channel.
