The DDSY168 -S consists of two parts. A customer interface unit (CIU), and a metering and control unit (MCU). A CIU is a keypad based display, to be installed within consumers homes wherever there is a plug point. A MCU is the main meter, installed away from consumers home in a kiosk, meter box or a pole-mounted enclosure .MCU communicates with CIU via wireless communication such as Power Line Carrier (PLC), Radio Frequency(RF), and LoRa.
Key Benefits
1) Quick and easy installation with no need of accessories
2) Reduce operational and inventory cost
3) Two way communication with AMR AMI server(on request)
4) Flexible payment control through various element settings
5) Meter provides information by inputting short codes
