Parameters of MQTT Modem

• 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 can realize long-distance data transmission of one to one, one to many and many to many.

Customers do not need to develop the server, but configure the cloud networking function of the device.
