High-Speed Measuring-Transducer Inputs, Voltage/Current (via IO210, IO212)
NOTE
i i
Current and voltage must not be connected at the same time to one measuring-transducer input. Instead,
only connect either current or voltage. For EMC reasons, do not connect a line to an unused input (current
or voltage).
Use shielded cables.
