ZHC4013 4G Modbus DTU supports 1 channel RS485 transparent network IO products, compatible with Modbus RTU/TCP protocol, JSON. With “remote control” as the core function, it is highly easy to use, and users can easily and quickly integrate into their own systems to realize LTE, RS485 remote and local control.
