Product Description

RS485 IOT Cellular Modem GPRS Communication Router for Data Acquisition

 

  • Introduction​ of IOT Cellular Modem

 

ZHC2921 is a network IO product that supports 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) output, 4-channel analog (current 4~20mA) detection, and 1-way serial port passthrough transmission. It is compatible with Modbus RTU/TCP protocol.With the function of "remote control" as the core, it is highly easy to use, and users can easily and quickly integrate into their own system to realize the remote control based on GPRS network.

  • Advantages of IOT Cellular Modem

 

  • Product ZHC2921 advantages:

  •  

     

    1. Simple and diverse networking methods

    The equipment is powered on, and the parameter interface is configured to realize remote supervision. At the same time, a variety of solutions are provided, which are suitable for different application scenarios and cost saving.

    2. Save labor cost and reduce meter reading error

    Realize automatic meter reading, ease the labor intensity of meter reading personnel, reduce the error of meter reading caused by human factors.

    3. Efficient management

    Online management of occupancy, remote meter reading of housing resources and background data of tenants are clear at a glance, improving management efficiency and reducing operating costs.

    4. Save hardware costs

    No additional collector, support active collection, easy to use, just need to configure in the configuration software.
