Schneider Electric NTSDDO1602XAHK Modicon Edge I/O NTS Digital Output 16Ch 24VDC Hardened Remote I/O Module

The Schneider Electric NTSDDO1602XAHK is a Modicon Edge I/O NTS discrete output module kit with 16 transistor outputs at 24 V DC, 500 mA per channel, split across 2 groups of 8, pre-assembled on its NTSXBA0200H base for severe-environment use. Channels wire in 1 or 2 wires and draw field power from an external 24 V DC supply, running across an extended -40...70 degC range with conformal-coated electronics. It mounts on a DIN rail and connects to Modicon M262 or M580 controllers.

Selection Notes

The 500 V AC group-to-group isolation on the NTSDDO1602XAHK means a field-side fault on one 8-channel group does not propagate to the other, worth the wider 30 mm footprint when the panel drives two electrically separate load circuits. External 24 V DC field power keeps output current off the internal bus supply, so size that external supply for the full 8 A module rating. The hardened build's conformal coating and -40...70 degC range are the reason to choose it over the standard NTSDDO1602XAK when the enclosure sees vibration or condensation.
