- Introduction of MQTT Modem
ZHC492S 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.
Client can send Modbus commands to ZHC492C through the network and
serial port to read and write DO status.
DO of ZHC492S support active reporting, restarting the holding
relay status, output holding time, timing flip.
ZHC492S 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.
