Best connection Best connection of a NPN open-collector output encoder to an input unit
Condition: R
L
must be dimensioned to ensure the specified encoder output
current range.
¾ If procurable, connect the encoder to an interface as shown above.
The integrated load Resistor R
L
mostly is dimensioned to ensure a load
current range up to 15 mA, so the encoder output will not be overloaded.
The signal operating level of some input units can be selected by hardware or
software to NPN or PNP. NPN is required in this case.
¾ If not procurable, use a signal coupler.
Such a coupler works identically to the drawing shown above. See any
examples that could be used as follows:
