Measurement Value Output
optoNCDT 1402
Measurement Value Output7.
The optoNCDT1402 can issue the measurement values either via the analog output or the RS422 serial inter-
face. The two different types of output cannot be used concurrently.

Calculation of measurement value x in mm from analog current
Reference value SMR Reference value MMR:
x [mm] = (I
OUT
- 4 mA)*
MR [mm]
16 [mA]
x [mm] = (I
OUT
- 4 mA)* - MR/2
MR [mm]
16 [mA]
Example: Measuring range = 10 mm, I
OUT
= 12 mA; Result: x = 5 mm or x = 0 mm
