  • Introduction​ of MQTT Modem

 

ZHC492C support 4-channel dry (wet) node detection, 4-channel relay (COM, NO, NC) Output, 4 channel analog quantity (current 4~20mA) detection, 1 channel RS485 transparent network IO products, compatible with Modbus RTU/TCP protocol. With remote control as the core function, it is highly easy to use, users can easily and quickly integrate into their own systems to realize remote and local control based on LTE, RS485.

 

 

  • Function​ of MQTT Modem

Client can send Modbus commands to ZHC492C through the network and serial port to read and write DO status.
DO of ZHC492C support active reporting, restarting the holding relay status, output holding time, timing flip.

 

ZHC492C Function Description
Support serial port timing to send heartbeat
Send Modbus commands to ZHC492C through the network and serial port, you can read and write DO DI status, AI value
ZHC492C DI DO supports active reporting, restart to maintain relay status, output retention time, timing flip, etc.
(If there is no DI status change after power-on, it will be reported cyclically according to the "cycle time". If there is a DI status change, all status will be reported immediately and the cycle time will be reset.)

 

Application of MQTT Modem

 

1. Automatic Soil Moisture Monitoring
Establish a soil information system to master the overall quantity, quality and spatial distribution of soil resources.


2. Automatic Weather Monitoring
Improve the accuracy of weather forecasts to provide a scientific basis for governments at all levels to prevent and reduce disasters.
