Schneider Electric NTSDAI0403HK Modicon Edge I/O NTS Digital Input 4Ch 24-48VAC/DC Hardened Remote I/O Module

The Schneider Electric NTSDAI0403HK is a Modicon Edge I/O NTS discrete input module kit with 4 inputs rated for 24 V AC or 48 V AC/DC, pre-assembled on its NTSXBA0100H base for severe-environment use. Channels wire in 1, 2 or 3-wire sink mode 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 dual AC/DC rating on the NTSDAI0403HK means the same 4 channels accept 24 V AC pilot signals or 48 V DC/AC field contacts without changing hardware, useful when a panel standardizes on one module across mixed-voltage zones. Choose the 100...240 V AC NTSDAI0215HK instead for line-level inputs, or a plain 24 V DC NTSDDI module when the field devices are all low-voltage DC. The fixed 9.28 ms filter is not adjustable on this variant, so it is better suited to steady-state limit-switch signals than to fast pulse counting.
