Product Introduction:
SR-888 Data Concentrator Unit is the transfer station of Wamr Net system to perform remote uploading of metering data. Its main function is receiving data from SR-868 Data Collector and transmitting data to the remote background platform through GPRS network. The key component of SR-888 Data Concentrator Unit is one of our most widely-deployed RF modules working on formulated frequency for meter reading. SR-888 can manage all the SR-868 Data Collector within its transmission range and upload metering data anywhere covered by GPRS signals. The Data Concentrator Unit is supplied by 220V (50Hz) civilian AC power. Built-in regulated switching power supply has ensured reliable applications in complex environment.
