※ 3. Input/Output is different by option. Please refer to 「Ordering information.
※ 4. For supplying power for transmitter, it is recommended to use shield cable to reduce noise.
※ 5. RS422/485, Ethernet, USB device communication outputs are not used at the same time.
※ If sensor input line is longer, it is recommended to use shield cable to reduce noise.
