Limit Switch Port​

  • Please pay attention to the wiring order. For three-wire limit switches, note the connections for 5V, GND, and S. Incorrect wiring may cause motherboard damage.
  • For two-wire limit switches, simply connect S and GND.
  • PL08 and other proximity switches require an external diode on the signal port to reduce the voltage below 3.3V.
