Plug-in PLC communication module
CM1yS is the series of plug-in communication modules designed for easy integration of modular meters in AMI systems. They provide data exchange between electricity meters and data concentrators over the low-voltage network (S-FSK or G3-PLC). Communication modules are simply mounted under the terminal protective cover and use RS485 port for communication with the meter. Meters with installed communication modules are compliant with IEC 62052-11 and IEC 62053-21. All modules support DLMS/COSEM protocol.
