E820-AIO is the analog signal collection product designed by Ebyte.
With RS485 communication network, E820-AIO transmits the analog signal
of scattered field data point via AD transformation to master or control
remote home site via the PC. Built-in watch dog (0.2s reset), the system
won’t be halted easily. E820-AIO analog acquisition module features
measurement data collection, measured data collection, device switch
status collection etc, mainly used for the data collection, controlling and
device display of various measurement and control terminal, suitable for the automation and information
systems in various industries.
Features
