FP0
Internal circuit
r: Internal resistor of limit switch (kW)
R: Bleeder resistor (kW)
The OFF voltage of the FP0 input is 2.4V, therefore when the power supply voltage is 24V, select R so
that the current will be greater than I =
The resistance R of the bleeder resistor is: R ≤
The wattage W of the resistor is: W =
In the actual selection, use a value that is 3 to 5 times the value of W.
