The inputs are protected to 200V. However, if an input terminal's voltage exceeds +14.25V as referenced to module common, channelĆtoĆchannel
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.
