E820-AIO(UI-485-4-5)

[Collection]:Analog signal

[Signal type]:0~5V

[Communication level]:RS485

[Size]:82*84*25mm

[I/O channel]:4-channel

[Feature]: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.
