High-Speed Measuring-Transducer Inputs, Voltage/Current (via IO210, IO212)
i i
NOTE
Current and voltage must 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.
