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.Only 8 volts can be placed directly across the input when configured in the current mode.Refer to publication 1770-4.1, "Programmable Controller Wiring and Grounding Guidelines."Availability: In StockEstimated Lead Time: Usually Ships in 5 - 7 Working DaysShipping Weight: 2 Kg
