MBUS/RF/PLC communication, Split type(MCU+CIU)
The DDZY876 is used for a wide range of smart prepaid metering applications. Is split type, consisting of two parts, the MCU(Metering & Control Unit) and CIU( Customer Interface Unit). The CIU is installed within consumer’s home, while MCU is installed in a meter cabinet away from consumers.
DLMS/COSEM standard compliant.
IEC62056-21 Compliant optical port allowing for easy data interrogation.
Operate in both prepayment and postpayment.
Measurement of electrical parameters (Active energy, power, current, voltage, etc.)
Programmable load limit and low credit warning.
Detection and record tamper event such as opening main cover&terminal cover, current reverse.
Will cut off the power supply in case of overload after 5 minutes duration, no credit, opening main cover&terminal cover.
Downlink communication (between MCU and CIU) is M-Bus/RF/PLC,uplink communication would be RF/PLC.
Digits: 6 integers + 2 decimal
MCU LED indicators(1000imp/kWh, credit, alarm, comm)
CIU LED indicators( M-Bus/PLC: 1000imp/kWh, credit, alarm; RF: credit, alarm, comm)
