With 16-channel analog input, high sampling accuracy (≤ ± 0.1% FS), fast sampling rate, and outstanding signal stability. It supports inter-channel isolation design, effectively avoids signal crosstalk, and the input circuit has overvoltage and short-circuit protection functions. It meets international industrial safety and electromagnetic compatibility standards, and has strong compatibility. It can be flexibly matched with the same series of PLC hosts. It runs reliably, with a long average failure interval, and is suitable for industrial process control scenarios with 24-hour continuous operation.
