LK-GSM/GPRS Intelligent Multi-channel Wireless Transmission Instrument |
Main Features：
●Transmit analog/switch signals via GSM/CDMA/GPRS
●Configure via connecting to the instrument's built-in WIFI module with a mobile phone, which is convenient and efficient.
●1-to-many replaces wired transmission, featuring plug-and-play functionality.
●Transmission is possible as long as there is a mobile phone signal, with unlimited distance and extremely low power consumption.
●It can use an IoT SIM card, and there is no need to apply for a frequency usage license.
●Terminal acquisition can connect to PLC, industrial computer, notebook computer, single-chip microcomputer, etc.
