Signals & Systems India Private Limited
SANDS make of AMR Modem SAM-1101 is a smart electricity meter reading device that can be connected to any make of electronic energy meter by means of optical/ RS232 port, which is compliant to DLMS – IEC 62056-21 standard. The electricity meters measuring energy consumption can be located in either consumer premises or in distribution transformers. The modem draws its power from the meter terminal block and connects to the communication port of the meter. Thus this add-on energy meter reading system is non-intrusive and can be retrofitted easily to any meter. The Electricity Meter Reading device uses GSM/GPRS communication technology and has built-in intelligence to talk to the DLMS meter. AMR system is compatible with 4G network to push the power consumption-billing data, load survey data, and event data to a cloud-based server, with fallback options to 3G & 2G.
