Data Concentrator Unit
LY-DC12 is an advanced data concentrator equipped with a strong processor chipset, large data storage capability, and optional LCD; it also supports accurate metering functions, and transformer monitoring system. Its modular design provides a variety of reliable wired & wireless uplink and downlink communication channels addressing a secure and future-proof data transaction platform. This range of communications can be a local physical port like IR, RS232, RS485, USB and remote downlink PLC, RF or NB-IoT communications as well as GPRS/3G/4G/Ethernet uplink channels.
LY-DC12 is designed fully complying with DLMS/COSEM and IDIS standards to easily and securely provide interoperability over different worldwide metering and system vendors.
