twisted pair cable. The power rise timing should be the same for all stages.
[1] Example of supplying power from one power supply
[2] Example of supplying power from multiple power supplies
Caution
1. Use a common 0-V line for the power supply connected to each stage.
2. Be sure to install the RABU unit (simple absolute R unit) paired with each RPCON unit or RACON unit in the same row
(stage) as the applicable controller unit.
3. Keep the total distance of internal SIO communication lines of the ROBONET system (distance from the Gateway R unit
to the terminal resistor of the last controller) to 30 m or less.
