Product Details
Industrial 2G IOT Cellular Modem Multi-Purpose Wireless Cellular
Data Transfer Unit
- 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.

- Solution of IOT Cellular Modem
Remote Intelligent Wireless Remote Meter Reading
Zongheng intelligent control combined with the existing Internet of
Things technology, using 2G RTU+ smart meter + cloud
technology.Connect 2G RTU and smart electricity meter together,
collect the electricity meter data, send it directly to the server
through GPRS network, deploy to the server on the management
platform, through the platform, the administrator can real-time
view the electricity consumption of each floor of each meter.
