Edge Computing Gateway, PLC Gateway
ZHC1921 is a network IO product that supports 6 channels of dry (wet) node detection, 4 channels of relay (COM, NO) output, 4 channels of analog (current 4~20mA) detection, and one serial port transparent transmission. It is 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 into their own systems to realize Remote, LAN and local control of Ethernet and RS485.
