≤ R (kΩ) ≤120
E (V)
The load resistance of pulse output should be used to 1kΩ, 2W.If no translation of the pulse output possible by the cable length or the frequency of the pluse output,the load resistance should be selected by calculation as shown below.
Example of CEV cable capacitance 0.1µF/km
WhereE = Supply voltage (V) f = Frequency of pulse output (kHz)R = Value of load resistance (kΩ)
C = Cable capacitance (µF) P = Power ratio of the load resistance (mW)
P (mW) =R (kΩ)E2 (V)
Example 3In this case, No communi-cation is possible (when shielded cable is not used).
The range of load resistance R for the pulse output.
Example 1In this case, Communica-tion is possible(up to adistance of 2km when aCEV cable is used).
Example 2In this case, Communica-tion is possible (up to adistance of 200m when a CEV cable is used) and R = 1kΩ).
In this case, Communication is possible (up to a distance of 2km when a CEV cable is used.)
In this case, No communication is possible.
In this case, No communication is possible.
