Limit Switch Ports

• Please pay attention to the wiring sequence. For three-wire limit switches, note the connections for 5V, GND, and S. Incorrect wiring may cause damage to the motherboard.
• 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 to below 3.3V.
