1. General DDS*8u single-phase multi-function PLC watt-hour meter is designed as the terminal of Automatic Meter Reading (AMR) system. It can communicate and exchange the data with concentrator via power line. The meter can freeze the energy in the end of the month so the AMR system can read the data automatically in meter reading day. The performance of meter complies with the standard IEC****6 and IEC *******1 DDS*8u is the multi-function and multi-tariff meter, it has four tariffs and can measure total active energy consumption in different tariff period. All data and parameters are stored in non-volatile memory. Remote control is one of the most important features of DDS*8u. AMR system can cut off the power supply through switch off the relay inside the meter. The meter can also act as the repeater, xxxxx AMR system can read the data in the DDS*8u through maximum 3 levels to the destination, this function improve the reliability of AMR system a lot. Functions âï¿&frac*2; Energy display by LCD, maximum 6 integer and 2 decimal âï¿&frac*2; Normal and reverse connection energy measurement âï¿&frac*2; Four tariff and *0 time zone are definable âï¿&frac*2; PLC data transmission based on CDMA technology on **5kHz Spread Spectrum Carrier. âï¿&frac*2; Remote control âï¿&frac*2; Programmable via HHU or PLC âï¿&frac*2; Anti-tamper functions include reverse connection, short connection and so on. âï¿&frac*2; Alarm for overload, reverse connection, clock battery low and so on âï¿&frac*2; Maximal consumption can be limited âï¿&frac*2; History data reservation in non-volatile memory. âï¿&frac*2; Event records âï¿&frac*2; Time synchronization and correction âï¿&frac*2; Pulse output Notes: For the details of the functions, please see the TECHNICAL DESCRIPTION.
