WARNING! According to international standards,
applying voltages below 50 V (DC or AC) and above
150 V (AC or DC) simultaneously to the digital inputs
and/or outputs of the RDIO-01 is not allowed.
Additionally, only voltages of the same nominal level
should be applied simultaneously to digital inputs DI2
and DI3 due to reduced isolation voltage.
Note: Do not route signal cables parallel to power
cables.
