  1. The inputs are protected to 200V. However, if an input terminal's voltage exceeds +14.25V as referenced to module common, channel to channel crosstalk can cause invalid input readings and invalid underrange/overrange bits.
  2. Only 8 volts can be placed directly across the input  when configured in the current mode.
  3. Refer to publication 1770-4.1, "Programmable Controller Wiring and Grounding Guidelines."
