Best connection option of an encoder with NPN open-collector output to an input
device
+V Operating voltage 0 V Grounding
R
LI
Load resistance
Requirement:
R R
L
must be dimensioned for the specified output current range of the encoder.
4
Connect the encoder to an interface, following the illustration above as best as possible.
The integrated load resistance R
L
is generally dimensioned for a load current range of
15 mA so that no overload occurs at the encoder output.
The signal level of some input devices can be set to NPN or PNP via the hardware or via the
software. In this case, NPN is required.
4
If this is not possible, use a signal coupler.
The function of a signal coupler is shown in the illustration above. The following can be used:
WAGO Electronics terminal with optocoupler. Reference no. 859-758
PHOENIX Input optocoupler Type: DEK-OE-24DC/24DC/100KHz
WEIDMÜLLER Optocoupler Waveseries Type: MOS 12-28VDC 100kHz
