DDZY876 1P2W STS METER PLUG & PLAY COMMUNICATION MODULE

Pluggable communication module with different solutions

The DDZY876 is used for a wide range of smart prepaid metering applications. 

Option for communication module supports both GPRS+PLC(G3) communication. When one communication method experiences poor performance, it automatically switches to the other, ensuring highly reliable two-way communication with the AMI system. 

The auxiliary terminals support RS485, RS232, RJ45, and MBUS, etc.

  • DLMS/COSEM standard compliant.

  • IEC62056-21 compliant optical port &VTC allowing for easy data interrogation.

  • Operate in both prepayment and postpayment.

  • Measurement of electrical parameters (Active power, reactive power, current, voltage, maximum demand, etc.)

  • Programmable load limit and low credit warning.

  • Detection and record event such as cover opening and terminal cover opening, current reverse, bypass, etc.

  • Downlink communication MBUS, uplink communication GPRS+G3 PLC.

  • Digits: 6 integers + 2 decimal.
