Ethernet Analog Transmission Gateway
ZHC1661 Ethernet Analog Transmission Gateway is a network IO product that supports 4 channels of analog detection (current 4~20mA), 2 channels of analog output (current 4~20mA), and one serial port transparent transmission, compatible with Modbus RTU/TCP protocol. With “remote control” as the core function, it is highly usable, and users can easily and quickly integrate it into their own systems to realize remote, local area network, and local control based on Ethernet and RS485.
