Schneider Electric NTSDAI0404HK Modicon Edge I/O NTS Digital Input 4Ch 100-120VAC Hardened Remote I/O Module

The Schneider Electric NTSDAI0404HK is a Modicon Edge I/O NTS discrete input module kit with 4 channels rated for 100...120 V AC, pre-assembled on its NTSXBA0100H base for severe-environment use. Channels wire in a 1 or 2-wire sink connection and run 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 100...120 V AC rating on the NTSDAI0404HK matches field devices wired to a single-phase line voltage common in North American and Japanese panels, where the 240 V-rated NTSDAI0215HK would be the wrong fit. The hardened build adds conformal coating and the extended -40...70 degC range over a standard K-suffix module, which matters in panels exposed to condensation or wide ambient swings. With only 1 or 2-wire connections supported (no 3-wire shielded option), it is best suited to short local wiring runs rather than long field cable pulls.
