The connection of a NPN three-wire sensor with a noise filter is shown in the next figure.
HS_GPI pull-up resistors
Pull-up resistors ensure the desired logic state when the sensor (transistor or relay) is in off-state.
NPN pull-up resistor value must be chosen in order to ensure a positive value in the differential receiver
while consuming low current. For a sensor supply of 5 V, 1 k
Ω
is recommended. For a sensor supply of
24 V, 47 k
Ω
is recommended.
