Mini data concentrator for AMI Solutions Plug - in module , single phase PLC RS485 GPRS connect to HES
The mini concentrator is a superb data collection device in multi-dweller and multi-apartment building or complexes. It connects the meters via RS485 communication and can accommodate up to 64 pcs. Its uplink to head-end master station is GPRS. It can relay the data transfer, reduce the network burden, and backup the entire metering system structure.
In the places where many meters are situated closely within one limited space, mini-concentrator is the most economic and reliable means of managing various meters.
Main Features
1) GPRS for data exchange with head-end server (HES)
2) IR optical and RS485 serial port
3) Real-time meter readout
4) Remote load management control over sub-meters
5) Non-volatile memeory for data retention in absence of power
6) IEC 62056-21 and DLMS/COSEM compliant
Utility benefits
1) High stability
2) Reduced operational and maintenance cost
3) Free to choose suitable communication according to local needs
4) Remote contractual setting with meters
5) On demand and load shedding intrusive control over meters
6) Long life time design with easy upgrade features
