Minimum -40 dBm ± 2 dBm
Spectrum 400 nm to 1100 nm
Attenuation In the case of plastic optical fibers, you can expect a path attenuation of
0.2 dB/m Additional attenuation comes from the plug and sensor head.

High-Speed Measuring-Transducer Inputs, Voltage/Current (via IO210, IO212)
NOTE
Current and voltage may not be connected to a measuring-transducer input at the same time; only either
current or voltage may be connected. Due to EMC, no line may be connected to an input that is not used
(current or voltage).
Use shielded cables.
