ZHC495C is one kind of a 4G RTU with 16 channels 4G Network IO Controller. It supports 8 Road dry (wet) node detection,8 Road relay (COM, NO) output, 1 channel RS485 transparent transmission network IO products, compatible with Modbus RTU/TCP protocol. With “remote control” as the core function, it is highly easy to use, and users can easily and quickly integrate it into their own systems to achieve LTE, RS485 remote and local control.
