Industrial RS485 Serial To Ethernet modem Analog Data 4-20mA Acquisition RTU

Parameters of ZHC1661

Introduction​ of ZHC1661

ZHC1661 is a network IO product that supports 4 channels of analog detection (current 4~20mA), 2 channels of analog output (4~20mA), and 1 serial port (RS485) transparent transmission. It is compatible with Modbus RTU/TCP protocol. With "remote control" as the functional core, it is highly easy to use, and users can easily and quickly integrate into their own systems to realize remote and local control based on Ethernet and RS485.

• Function​ of ZHC1661

ZHC1661 can connect with host computer or PLC through RS485 communication interface and serial communication, and transmit data of each channel to host computer.Adaptive Modbus RTU/TCP protocol, what format of data is sent to the cloud, what format of data will 1661 reply to. Support one-to-one, one-to-many connection, Also can communicate with PLC.
